hey i need the part number for ls7 lifters and what gaskets should i use im going to install stage 2 317 heads on my lq9 also i need the part number for arp head bolts or are the oem ones better? any help thanks

 

GM 6.0L MLS Head gasket - 12589227
GM LS2/LS7 Lifters - 12499225
GM LS2 Lifter guide/tray - 12595365
ARP 97-03 LSx Arp Head Bolts - 134-3609

I usually buy my parts from www.texas-speed.com

 

ok so the oem head gasket will be fine i plan to run 12 lbs of boost the most

 

Oh if you are going to run boost then I'd wait for someone else to chime in.

 

thanks for the honesty hopefully some fi guys chime in soon....

 

The GM MLS heads gaskets are great for boost. The are numerous cars cars and trucks on PTnet and LS1Tech that run up 20lbs+ on them.

The ARP head studs are always good insurance but not at all required for 12lbs. Plenty of guys still runnign the TTY stockers (new ones of course). You don't generally hear about people pushing water (from lifting their heads) till the high teens. The key of course is the correct tune.
