hey guys, i'm posting for a buddy. we got a forged 347 ls1 with stock 243 ls6 heads, an epp blower cam, and a 15# pulley on a d1sc procharger. the car runs stout, but he just popped a gm mls head gasket. he's arp studded and has 9:1 SCR. the car is his street car and puts down 700hp to the wheels. since it's a street car, he's not wanting much maintenance. (how much non-maintenance is a 700rwhp car, lol!?). any suggestions are greatly appreciated.
