Port is pretty smooth actually, very balanced port design At .700 lift it's not too bad either...just at .630 to .680 it's a bit rough. I can't shape the short turn any better due to water close by. I'm putting a set on a 392 short block soon with 13:1 and a solid roller so we'll see what she does Brian Hafliger

I thought it would be cool if Indy would sell a version of this head with the pushrod hole relocated for offset intake rockers. I suppose that would would cut into their IndyBrock (sorry Josh thats what everybody calls them) sales though.

I'm off today and going to enjoy my family. No matter what they cost, they will always be cheaper than ANY other aluminum head out there and they will hold their own...I hope we shall see. Cost as always will be much cheaper than anything else out there making similar power with better components!! Brian Hafliger

I can't price on here...they won't let me Yes you can put guide liners in or use a shorter guide. I can get more flow earlier too, as much as 15 cfm at .400 and 10 more at .500 but the port is noiser and stalls real bad...Flow is only part of the puzzle...air speed, port shape, CSA is very important and it's really a balancing act of all 'dem.

mopster member M Joined: Dec 2004 Posts: 128 Finland	146cfm rule is theoretical number for frictionless orfice without losses, you can�t use that for cylinder head ports. 350 fps is the limit for local air speed of the fast areas like short side floor or adjacent to pushrod wall, above 350fps you will have losses. If you calculate air speed for a certain CSA, you will have an average speed for that section, and thats approximately the number you see when you stick a pitot probe in the middle of that section of the port. If average speed of a section is 350 fps, its WAY too fast. Generally anything over 311 fps is not good. It can be higher than that but you need a better port design than small block mopar with std port location and std pushrod location.

The thing that bothers me about the Eddy victor BB head is no headers work on the tall deck...I know some headers can be made to work, but a lot of guys like to bolt on headers and go... Plus I'm an Indy dealer and between the EZ line, -1 line and SR line you can make good power. I've got a 540 BB mopar on the dyno now, 10.4:1 compression, 325EZ heads, 1050 on an Indy intake and solid roller for street and it made 745HP@ 6600rpm and 690TQ@ 4400rpm! That's a nice spread and TQ is over 680ft.lbs. for 900rpm! Ofcourse the heads were rubbed on a bit, but not too much. I'll post pics tomorrow nite Brian Hafliger

(class racing) Thinking about submitting the EQ head to NHRA for approval, would be nice to use a fresh set of castings instead of old wore out core shifted castings.

The Victor's exhaust port location is identical the MP Stage VIs (I've lined up both heads side by side to confirm this). I have TTI's 2" B/E-body headers for my Challenger that I used w/ my old Stage VIs and it'll be a bolt-in / no-change-required installation when my Victor-headed RB 452 goes back in w/ the TTIs. The TTI 2" w/ Victor or Stage VI heads are actually a better fit clearance-wise than my previous Hooker 1-7/8" Comp headers w/ OEM iron heads. The only downside is that the starter is captured by the routing of the tubes, requiring the driver-side header to be loosened up and pulled away from the engine to remove it. "Been there, done that." Also, TTI says their 2 to 2-1/8" Indy RB step header will also work, although I haven't looked into all of TTI's footnotes re: the application w/ Victor or Stage VI heads. I know the standard 2" header is a "no brainer" in my case and don't feel any need to change. I'd actually like to have seen a 1-7/8" to 2" step design offered, but that's just me.

Is it "better" if your port design results in measurements that fit within these ideals? Probably. Is it going to kill the head's performance if they don't? Nope. Example: My old Stage VIs were only 213-215cc ported, had a standard 2.20" x 1.20" entry w/ a pinch significantly less than that due to the nature of the port. They flowed 305+ at .600" and made over 600 HP on a pump-gas 440 (10.8 CR) w/ a .600" solid flat-tappet cam. That was enough to push my 3755# (w/ driver) street car to 10.5s at 126 w/ a full exhaust on DOT tires. FPS? Almost 400 over the short turn. Yeah, it would have been nice if the air speed was more in line w/ the ideals and "should" have performed better if they were. But that's what they were AND how they performed, regardless. This ain't Pro Stock stuff here...

Unfortunately, the port stalls hard when you go up in valve size...it stalls around .550 lift. Problem is the water below the short turn...just can't shape it properly.
