I've sent the 317 heads off to be checked already.. motor was pulled out still running due to a bent pushrod on one of the heads... everything else looks good.. I'm already looking at some parts to order and was wondering if i would have any P.V.C issues if i went with a T-ReX v.2 - 242/248 - .608/.612 - 110 lsa camshaft and Patriot Performance CNC Ported 243 LS6 / LS2 2.02"/1.57" 59cc Assembled heads??

 

59cc heads? The compression ratio will be high for a pump gas motor. You may want to do some calculations and get it closer to 11:1 for a naturally aspirated or nitrous pump gas motor.

 

If that's an LQ4 you should be ok, but you'll still want to check it.

 

I think it is a Lq4.. I pulled it out of a 2005 commerical chevy van...this is going into my 89 fox body mustang that i plan on running at the track only..
