is that the only diffrence?

i wish there was a edit button unless im blind but anyways so sences the heads on a s1 is off set that means the block is 2?

The block is the same. The ports are simply offset.

I'll get you some pictures when I get home. Can't view photobucket from work.

I didn't know the S1 heads on the L67 didn't have injector bosses drilled out. Interesting...

wait so if the blocks the same couldnt you put s2 heads and lim on a s1 block ?

ok i went to advance auto part online =p lol and i looked up head gaskets for 93 s1 and 99 s2 motor
and this is what i got

series 1


series 2

and theres the same besides the very top of the gaskets

and a couple holes

unless theres something i dont know (probly)
