Read AndyF's threads about his 505" with the EZ heads. He's had them over 800hp, although with some fairly exotic valvetrain. S/F....Ken M
If I recall correctly he was/is using TD rockers.. nothing exotic about them... just good

I run H.S. rockers and Manton rods with a Scott Brown solid roller, I don't think I will go beyond this level.
I was running a Scott cam in my W-9.. I didnt like it.. it gave up a lot of power.. he was/is big on the wide LSA like the 112 that mine was

So what do you run now?
I sold that engine and I sent a blank 48* cam with it so he can have what ever he wants to run.. I like the Bullit/Ulradye grinds.. I have a old MP cam in my 416 thats a roundy round solid roller grind with a 105 LSA and thats where I installed it.. its making 590hp for my street rod.. its actually more than I wanted for power since I only want to run 10.0

Thought he was running the paired Jesels, that's getting into the semi-exotic stuff, for an EZ head.
Not so exotic on B-1's and up. Just my opinion, obviously nothing set in stone. Heck, I'm looking at putting cut down NASCAR Ti valves into iron heads, just because I can, lol. S/F....Ken M

I'm running out of the box Indy EZ heads now but after port work will these support a 12.5 to 1 512" motor? And what gains do think I would see using the ported heads and going from 975cfm carb to 1050 on the 470"?
JMO.. but I would port the heads... I believe you will gain more in the head work than you would in the cubes and more than likely be a fair bit cheaper so you can invest the extra money elsewhere

I've been building and racing Mopar V8 for a lot of years, from street to NHRA class and S/class racing. I have not had a N/A Mopar V8 motor that liked wide LSA including some blown gas street Hemi motors I've tried a lot of different cams in a lot of different motors, all the SB Mopar I've raced or helped race like 106 or closer LSA and the BB, unless intended to be shifted above 8500 RPM like 104 to 110 LSA, not 111 to 114 no matter where the intake lobe center was degreed into The theory of opening the lobe centers up is based on RPM and HP and torque peak, wider LSA (112 or more)looses low speed(below7000 RPM) HP and torque and moves the peak up to a higher RPM like 7500 or higher. Closer LSA below 110, make more power down low, above 4000 RPM and peak sooner, 5500 to 7000 RPM I had a very good Mopar sponsored S/S 4 speed racer (Joe Alread, RIP) tell me years ago to concentrate on the first 100 ft. of the track, he said you get it right and the rest of the track will take care of itself That has worked very well for me Huh, Dominic

That's strange, went from a 106 to a 112 lsa on my 422 small block and it picked up 6 mph in the qtr. I only shift it at 7200 so I don't turnit that hard. It does go through the traps at 7600 at 162. It seems like all the engine master combos are going to large lsa also.
