I'm gonna have heads off what head is a direct bolt on that can give me a good boost without getting too crazy. I have an lq9 with mp112 and installing Lep blower cam specs 224/230 with 612 lift and 116 lsa. Thanks Alex

 

worked over 243 heads or l92 top end swap... unless you want to go aftermarket that is..

 

Would I need anything other than the head itself, I have patriot gold springs that's all

 

not for 243's.. l92 top end requires a few things

although 243's drop compression so you'll need to have them milled

 

243's wouldn't drop compression, they would raise compression, it'd be 10.9:1 like an LS2 if he had stock LQ9 flat top pistons.

Might want to talk to WCCH and look into a port/valve job/combustion chamber re-size (down a little to raise compression a little, but not too much to cause problems with detonation, and enhance squish area.) See what he recommends for your 317's, those were just my ideas.

 

wasn't thinking lq9.. they drop compression on 5.3 ad 4.8 though

 

Well ordered tsp stage 1 317 heads and I have patriot springs lets see how she does

 

Excellent choice, they should work great with your setup!

 

dont do a ported 243 head....send your 317 out for some work since you have a supercharger. they will flow just as good as the 243 and keep your compression where you need it.

 

Thanks for input guys , it's appreciated
