hi to all

i was wondring what would be beter to go for big CC heads to lower compretion with haier flow rating

or go with low comretion pistons on standerd heads

whin i install the livernoismotorsports 4.8-6.0L GM Truck Turbo Kit

witch well give mor space for boost and more power

thanks

Ask livernoismotorsports,they may say to do neither

 

Depends on your HP goals...

If givign the choice i would do pistons because you can upgrade them to forged pieces. Just a hell of a lot more work than slapping on some heads. I think in your case you have no choice unless you plan on buying hogged out aftermarket heads.

9:1 is a good all around compression for street and FI IMO.
