LS7 head gasket on LS2 block? I know some have reported problems using this gasket on the Gen III iron block 6.0L due to the coolant passages, but it seems like they will work fine on an LS2 block due to the siamese bores of the GEN IV blocks. Looking for a cheap solution compared to cometic gaskets for my AFR headed LS2.

I have AFR heads that require a minimum 4.135 bore gasket and maximum of 4.165. The LS7 falls right in that range at 4.150 and is a cheaper MLS option then cometic and is the compressed thickness I am looking for at .052

If they require 4.135 bore gasket, than the require 4.125 cylinder bore...
but you have ls2 with 4.00. Dont you find any absurd here??
I've just personally received my AFR 230v2 small bore. And their chamber diameter is 3.9ish. OEM ls2 will work PERFECT with them.
Patrick G on his G8 with 4.00 bore BUT with large bore AFR230v2 (that require minimum 4.00 bore) also used stock ls2 gaskets.

Just going off what Tony Mamo told me when he modified the heads for me. So you are saying I should use an LS2 gasket even if the chamber is larger then the gasket bore?

The heads are actually 205's with the chamber opened up for a 4.00" bore. I will probably just use the LS2 gasket, because after more inspection I think I pushed some water with the 4.130 gasket I have on there now.
