Looking for a piston thats works with a lq9 / l92 head combo Im build a forged LQ9 .030" over motor and a set of L92 heads. Looking to get about 9.5 cr for a turbo application, cam specs are 225 225 .581 .581 113 or might go a tad bigger to a 236 236 .587 .587 112.5, ive heard that there might be slight piston to valve issues depending on the piston used. Anyone used this combo before??

if you use a dished piston you probably wont have a problem with ptv. and the l92 heads have a 69 or 68 cc chamber i believe so you gonna want to run a dished piston anyways to get your cr down to 9.5.1. if your interested i have a set of 317 castings i would trade for the l92s since im not going turbo anymore. pm if interested. good luck with your build.

My fault, I was pushing really hard on it, truck weighs 6200 with me, not leaving on boost went 12.20 @ 112
goal is 10.99!! With a street truck driven everyday and pulling a "race car" to the track, unload the trailer and burn some **** up!
