Well I don't consider the header issue a big deal. There are some OOTB ones available and if you are doing a low deck there is no issue at all. I prefer to look at potential of a given part rather than ease of use or ultimate cost. Lord knows I am not an Indy fan per se but have used their stuff for sure.

I have not looked at seen or touched an SR head in a long time, so cost is not something I have looked at either. To me the potential would be the ultimate factor. Even if building a tall deck for an A body, can get headers made anywhere, and they will be superior to anything from a box. I have not done anything other than look at a TF head. Will see soon though as a friend who is an engine builder in Canada I think might be using them in an upcoming build. Be interesting to see what he manages to get from them. I understand the appeal of "budget friendly" heads that can just be bolted on using existing pieces as well. Budget is always a concern on some level.

Just don't hear much about the SR heads anymore. I had a set back in 2000 that we used on my 65 Belvedere. Just a little 451 pump gas deal in a street car. Std port window M1 intake small solid tappet cam, zero maintenance ice cream fetcher. Used to drive it to the track and when I moved to San Antonio it was my daily driver as well. It ran 10.50's that way at 3600+ lbs. on pump swill. Was a 47 mile one way trip to San Antonio raceway for me. Had a lot of fun with it for sure. First time I took it to Sonoma Raceway when I got back to California I ended up selling it as a nice gentleman was not letting me go home with it

I have always really liked the SR head, but like Dwayne says, its becoming hard to justify. This car has Sr's 505" bracket car, 8.70's, these have been on 3 cars now flawlessly....lol...and will most likely end up on a forth next year.

My early SR's were livened up years ago by the talents of Nick at Compu-flow and as a standard port window made some decent power.
BEST machine later on advised me that if a Max window and port were to be introduced, it would be a whole other world, but I stubbornly stayed in my ballpark till this day because I wanted to keep a small window and see what decent torque it could still muster in the lower lifts. Since then, the technology has changed for the best of both worlds and I guess I have to come up to speed literally.

I street drive, so low lifts is where it lives most of the time.

I'd think Trick Flow 240 heads would work for you given your focus on a standard port window and your focus on weight.

Hhhhhhhmmmmmmmm. Thank you.
I gather those TF's have a better flow at the lower end while utilizing a stock window. I must admit, I have not looked so much into them.
Yes, in my case, I figured that the weight or lack of it would not be asking too much of the engines breath to achieve a decent power level in keeping with a small tire on leafs.

Great info as I also enjoy reading post like this and learning how certain heads perform. Thanks Dwayne for posting this. Ron

Yes, not a cost prohibitive/ chase every cfm available effort. But definitely a major bang for the buck.

I quoted these separate, to ensure you know I am coming from a high-level of respect of your abilities. But, when I say 'low floor' I mean it still runs uphill to the shortside. Or, if there were enough material to raise the floor and the roof proportionally without increasing cross-section, flow would increase.

Got it.

I'm actually working on a set of SR's now that were originally done by Nick at Compu-Flow.
This customer has been running these for a number of years, and they seemed to be holding up quite well.
They were due for a freshen up so he sent them to me and asked to look them over and see if maybe I could get a few more cfm out of them.
Nick did a nice job, but it did seem like I could go after a couple of areas that might yield a little more flow.
The exhaust ports were working pretty good already, so my goal there was to just touch up the valve job and not lose any flow.

For the intake side i went with a different valve job, opened the pinch by .050, trimmed the guide boss more, and just tweaked the short turn a tiny bit.

4.375 bore, 28" test pressure, MW radius plate, same port before & after

Nice improvement Dwayne.
IIRC on my exhaust side that Nick worked, it was pulling 236 and change @600 lift.

If I hadn't jumped head-first (pun intended) into "Victor Land", I could see myself running SRs.

My M.W. non CNC ported SR heads where way better performing than my M.W. ported to the valve seat M.W. Eddy Victors are

Maybe you had the wrong person port them.

the Victors where done before I bought them from the guy I bought them from Same thing on buying the used SR and several sets of used 440-1
Be careful of what you buy used , especially unseen maybe
BTW, flow sheets and head flow from different head porters are not all the same when compared on another bench, huh

They're a little labor intensive compared to some of the other stuff out there(to really make them "nice")......but all in all they're still one of my favorite heads for the BB Mopar.

I have had the SR's on my Cuda for the last 20 years, actually purchased thru World Products, when I worked at the speed shop here, had them ported, and he said they flowed 325cfm at .650 lift, Indy claimed .350 at the time, but that was at .800 lift, and Ken Lazzari said we were on the money with my set.
My car presently has a 493, SR's, .601/.608 solid roller, 10.5 compression, 950HP, 2" headers, Indy single plane, car weighs over 3800lbs, runs mid-10s footbraking. I feel there's more in it, but the convertor is really tight, and I am not a great tuner, may want a 1050 as well.

100%I love reading this kind of stuff.
