I was thinking about buying a set of dart heads and a ls6 intake for my 370ci turbo motor. I been reading on the ls7 heads and intake what would be better? Im gonna be running at least a PT_88 or 91 and im looking for around 1000 at the rear wheels. I hear the ls7 heads flow very well with bigger valves only the 6.0 blocks can use.

The LS7 heads require a 4.125" bore. They do flow well: on my Procharged 427 (F1C) the engine made 773 RWHP on a fat tune at only 8 psi without methanol.

I would go LS7 personally. Or any of thos ET heads. The 255 would be sweet as well.

ls7 heads do not go on a 4" bore. if you have a 370, you have a 6L block, with 4.030 (or so) bore.

Does the LS7 heads have a thicker deck like the ET, AFR, DART,AllPro heads? That is one of the main reasons that people use them. Obviously for the power gains but th4e thicker deck allows for more pressure. Also what is the price on the LS7 heads? GL man

So you're saying they won't fit for his because they require that 4.125" bore eh?

go do some research in the ls2/ls7 section on this site, thats where i read all this info. its the same reason you cant use the new l92 heads (for a 4" bore) on an ls1/6 block.
