the time has come to finish assembeling my new motor and need some diffrent heads. i have 2 sets right now but neither are going to flow for this motor. currently have 14014416 58cc 305 heads and 354434 60cc 1.72"/1.50. im needing something that will flow above 5k rpm. was thinking about having the 434 ported out but im still not thinking they will flow that good. any help would be apreciated.
thanks,
chris

motor specs are 355sbc 4bolt main, forged crank, pink rods, speed pro flat top pistons, cloyes double roller chain, lunati 300deg cam at .515 lift, crane roller rockers, lunati push rods, edelbrock rpm intake 1"spacer whith a holley 750dp chokeless race carb, accel dist, msd wires, headman long tubes etc...

 

Fast Burns, many different aftermarkets such as AFR, Dart, World, etc.

What's your budget?

 

I use the 416 heads

have someone cut the intake seats to 1.94

hog the bowls and smooth them out and you will be happy

and you can say that you have stock 305 heads when you are asking for car lenths

 

Careful with the "hog" thing. You want to smooth them out, not significantly change the flow path.
