Default How would these do?

How would some texas speed prc 2.5 5.3 heads do on my lq9 ? What kind of rwhp would I see ? Would my mpg be affected? could I use them with boost down the road? Thanks guys.

raise compression to around 11:1 thus increasing hp and torque. with 228 and tbss intake, prob near 400 give or take. mpg shouldnt with more efficient head flow but since mo power, mo stompin, mo gas. compression too high for boost. good luck, rob.

I can just keep the 317s if I ever get around to boosting it. what cam would go good with my setup? I like some of the eps specs, want it ok a 111 or 110 cuz I love lope . Thoughts?
