yep im with you on that. i had ARP bolts in the old set up and was lifting them at 14psi. went to some studs and the LS9 gaskets and have had no issue. i might get some L19s or just go to some trickflow heads for the taller deck. or just lsx..lol well see

we did some of the work in the shop but about 3500 or so. a little less. but yes stock heads. 317 that came on the truck.

thanks man.. i was thinking 110 and the meth like i do on the street. but you say 114. im going to run it this week i hope, but im not going to push it to hard on 93 because i know it will be a diff load than the dyno, i backed it down to 15drg on the street for now..
