Vortecs to IronEagle200?
 

Well, after gaining 9mph, there is still need for a speed.
I thought that Iron Eagle heads w/200cc intake volume might
give some more power from 3500rpm up, without losing too
much from low end? Engine is 350/330HO w/crane cam 109821,
Air-Gap intake, BG650 carb, 9.3:1 CR, made 385hp@5200rpm &
450lbs@3200rpm on dyno. DeskTop2000 shows that there could be
near 30-40hp more with 200cc heads? Chris & rmbuilder, like to hear your
opinions, as well others with knowledge of real engine results?

Thank you,

Bob,

I`m using stock vortec heads w/1.94" & 1.50" valves. Only work on heads is;
removing sharp edges from chamber, unshrouding valves by head gasket,
blending the throats, reshape guides, 1 hour work total on both heads. And
of course machined guides to work w/higher lift cam. I was thinking of use
the same cam, w/1.6:1 rocker arms.
