Re: Head chamber size..??

That is exactly what I have in mind. I want to replace the rect port heads on my 454HO with a set of oval port units. Obviously I am planning on 219/188 valves, hardened seats, good hardware and porting work. Everyone tells me that a set of well prepared oval ports will produce more torque and low end street power for me. What is your opinion on the Gm performance aluminum heads, advertised as 110cc.???

Thanks, Tom
