A few more notes on the Victors:
1) The rocker gear can be more expensive for these heads due to them requiring at least a .650" offset intake rocker. Procomp, Harland Sharp, Hughes Engines, T&D, and Jesel all makes them. The Hughes stuff is about $600, T&D is $1100, and Jesel is (!!!) $1660. For a street car with a endurance type roller the Hughes seem to be the best value. There is not much data/feedback on these heads and the hardware available to run with them yet. I am going to run a large roller cam so most likely T&D's will be my choice. I need to ask the guys at Hughes what they think about running .750+" of lift with their rockers.
2) If you are running a low deck engine (9.98" like a 400 block) and decide to go with a max wedge port window like the heads above there is one place that makes intake manifolds for your engine (Indy Cylinder Head). The do make a single four for both 4150 and 4500 series carburetor flanges as well as a tunnel ram. I will test a 4150 series 1050 QF carb with annular boosters as well as a tunnel ram with 2 1050 QF's on the dyno when we get that far so stay tuned there. I am sure we will try a dominator as well with 4150-4500 adapter.
3) Headers can be an issue due to the raised exhaust ports. TTI makes headers that work however I think some headers might have issues with the torsion bar, especially with the RB platform (10.98" deck).
4) If you buy your heads un-prepped be prepared to spend some time cleaning them up and deburring them. The latest set of Victors I have must have been machined right before they freshened up the tooling. The push rod holes in the deck surface of the head also will need to be opened up.
I am going to eventually get a set of pro comp heads and send them out to the budget porting place. I estimate they will be about a total of $1500ish fully CNC ported with max wedge intake port windows. That will be over $1000 cheaper than a set of CNC ported MW port window Edelbrocks but there are trade offs with the imported heads. Helicoils, core plugs, etc are different and those things are not as important in some applications as others, ie street cars with solid cams vs. strip cars with big roller, etc.
Hopefully this helps. I think if a guy is shooting for 650ish HP with a 500" short block the Indy EZ's or RPM's can get you there much cheaper if you already have headers, etc. I am changing most of that stuff on my car when I change to my new Victor headed pump gas engine so it is a wash. Every time I drive my car in it's current configuration I am amazed it has lived to long without a failure of some sort. With all of the hard miles on it I don't want to reuse anything in my new engine.
