My viewpoint is somewhat in contradiction to Jesse’s.
Brads motor made close to 700hp from 452 cubes with std port Victors that didn’t recieve any extraordinary reworking, with a 4150 carb and an ootb intake. Still had a low tech Hemi pan on it as well....... no vacuum pump, no gas ported rings. It also had an easy-on-parts cam in it.
I have no doubt that same basic combo could be tweaked to find another 20-30hp without doing any more work to the heads.
The way I look at it....... how bad can they be? 350cfm from a true std port head with normal porting.
They don’t need to be the best head ever made, or the easiest to use, or the best bang for the buck....... to still be a decent head.

My tendency to be flip & sarcastic doesn't necessarily convey everything accurately. My Victors may not have been "bolt on and go", but the end results do speak for themselves.
If I thought they were such a P O S I wouldn't have bought another pair at a good price that are up at Dwayne's to have some basic prep work done to them before I decide what's next.
Some things don't have to be as complicated as people (especially like myself) can make it. It's very much self-inflicted, and I readily acknowledge this.

... And .003"+ excessive piston clearance on a .060" oversize block that couldn't be re-honed w/ a torque plate cuz the bores distorted too much to clean up properly. It just got touched up w/o the torque plate, and I used MLS gaskets to try and reduce some of the distortion that a composition gasket would allow. If nothing else, the bottom end is "well seasoned".

I remember when I bought mine.Summit had a good deal going on them. I also considered Indy SRs but when I asked Russ at Indy a question,he treated me like crap. I swore that I would never buy from Indy. I got the 440-3X from a Moparts member at a good price.

You know, I like the Indy stuff, the parts seem to make good power, but I was treated the same way by Russ, both on the phone and in person. I do not have a single Indy part on my engine, and it has ran a best of 9.65 @ 140, one of Russ's many remarks was that basically I was too dumb to build an engine that would go in the 9's just buy a complete one from Indy. I explained to Russ or tried to, that building the car to me was more fun than racing it. And I know, my engine could be a little faster with Indy stuff, but who cares, its all index's or dial-in's anyway.

The steps i performed to get my victors ready:
Used +.050 locks and .050 keepers to achieve a 2" installed height. Sourced correct (longer) studs for rocker shafts Deburred castings Corrected rocker geometry by moving shaft .090 up and .090 away from the valves Grind for pushrod clearance
I don't see anything different going on with the set of -1s that we have either.
With a standard +.100 BBC valve the installed height is not anywhere close to 2". In fact I will most likely use the same Ti locks/retainers and Isky (PSI) RAD springs that we have on the victors. As far as geometry if i were installing longer valves (+.200 BBC valve i.e.) to gain installed height the jesel rocker bar would have to (gasp) move up and back to create an acceptable sweep pattern. Sounds like these two heads have parity if you are trying to run a common 2" valve spring. And yes it seems like heads that have large ish ports will want a +.700 lift roller cam to make power per thier design. I crigne when I see people using flat tappet stuff at that level. When the list of compromises gets long it see,s like the hp and rpm fall off. It all depends on your desired service intervals and intended use.

I don't have any run time experience with the Victor head but I was able to push the Indy EZ head out past 900 hp using fairly conventional parts. Stock valves and valve locations but the heads were ported and then touched up by some of the best in the business. The trick was the Jesel rocker arms which allowed me to run up to 0.880 lift. I used a cam with 0.481 lobe lift and either 1.70 or 1.85 rocker arms depending on what I was trying to do. I'm not sure if the same trick would work on the Victor head but if I was trying to make big power it is probably something I'd try.It does work on these There is a limit to the shaft rocker arm system although the limit is probably higher than where this engine is at the moment. I think the limit is somewhere around 800 hp but I'm sure people have pushed the stock type shaft system past that. Even with the Jesel setup it does take some time to figure out how to get close to 0.900 lift. There are only a handful of springs made that will work and they require specific cups, retainers and locks. I had a whole drawer full of that stuff that I would mix and match. I eventually ended up using a spreadsheet just to keep track of the different combinations. I think I was close to a 2.100 installed height using the stock valves that came in my EZ heads from Indy. This is good info^^^^^^^ FWIW I made 780HP @ 466 cubes with .750" and T&D's single shaft system with 1.6/1.6 rockers. So I guess I would say the same as you. Had I been smarter I would have milled the rocker stands off and machined.....etc...... The single shaft system is what hampers all single shaft systems and had I ditched that could have made my life much easier. J.Rob

I have a 512, procomp victor copy heads, around 12 to 1 comp, 1.6 rockers, .740 lift cam, Manton pushrods, hand ported in my garage, homemade intake with two AFB's for NSS, 3200 lb car ran best of 9.65 @ 140mph, dyno said 725HP nothing exotic, I think that is about the goal you set in your post. The engine ran for 10 years with one freshing, bearings and rings. Last summer it broke a rod, going back together as a 540. will see how it does in that version soon. My flow numbers on the heads at max wedge port size were close to what was posted in this thread. I bought the cheap procomps, because I did not want to screw up an expensive set porting them myself, I am pretty happy with the results per dollar spent, and reliability. I would guess a good single plane intake with a dominator would make it at least a tenth faster, maybe more.

At those cubes and 12.5.1 comp, I'd definitely put a bigger solid roller in there after you test what you have unless it get's yer goat and makes ya happy..........
