i have been reading like crazy and have mixed reviews. i just picked up a 5.3 truck block. now my question is do i use the 706 heads or use the 241 heads?? this is going to be a turbo motor. next question is what cam? z06? and what valve springs should i go with? just need some guidence please. sorry if this is a repeated question.. thanks tony

 

Maybe try the forced induction forum???
Probably lots of build info there....

 

706's have a bad rep due to issues with the foundry that cast them. If there is a battery logo on the head around the rocker bosses, they are the problematic head.

241's would probably be a better head. You'll start off with larger valve sizes and they don't have the issues with cracking around the bolt holes like the 706's do.

 

awesome!!! thank you for the reply

 

lol, i did and it has been on there for a few days and no answers on it. thanks anyways
