487x heads

i had these heads with 194 and 150 valves stock,no port work in a 88 camaro with 3.42 gears 700r4 stealth intake,750 edelbrock carb,headman headers,268 comp xe cam,355 with flat tops,ran a 13.45 with street tires and dyno'd 297horsepower at wheels.so i think these heads with port work might support 400 horsepower at flywheel with a more aggressive camshaft.

Yes, you can get 400hp out of them. They will need full full porting and shave the decks .050-.060 to increase the compression ratio. If the piston is below deck at TDC use a thin head gasket.
Lunati Voodoo #60104. You'll need a converter swap and want to recurve the distributor.
