I know there's alot of questions about this but this is the place to ask, ok I have a complete l98 in my car with the 193 heads and I also have some 305 601 heads, I'm pulling the motor and going to port the heads since it's out, which heads should I use, everyone I've been talking to is telling me to go with the 601 heads, what do you guys think, the pistons are the 4 valve relief pistons with a roller cam, any help will be helpful

 

Come on guys,

 

i put the 305 heads on my 350 and im running an 11-1 compression and it definitely gave me a boost in torque .. i have to run premium or higher no though otherwise the engine pings

 

How is it a "complete" L98 when it has 193 heads? What's your compression ratio going to be if you put on the 601s?
