Six bolt heads? I have a new GM LSX block with the option of six bolts per cylinder for the heads. I am having a hard time finding this option in a lot of the heads i am interested in, such as LS7 heads. Does anybody know where i can find six bolt heads? Maybe a stupid question but im new to this LS thing. Have just built old school 350's until now.

I don't believe any GM castings are six-bolt. You are going to have to look at aftermarket heads such as AFR, Warhawk. What type of engine are you building?

Im wanting to build a 440 with about 600-700 FWHP N/A. I know that 4 bolt heads can handle this no problem but i might want to super charge it later without having to go buy new heads.

If your willing to spend some money give Richard at WCCH a call and get some allpros. Do not buy warhawk heads. They do not line up with the GM 6 bolt block. Also don't hold your breath on those GM heads. The last time I spoke with the GMPP reps they said they were 1 year out on the head min. That was around 8 months ago but since then they had that litle financial problem and put there performance parts division on stand by.
