Head gaskets
Building a 406 SBC, 4.155 bore. Like to hear some opinions on Cometic MLS head gasket bore recommendations. 8.0 - 1 Compression, 8-71 with 9 pounds of boost. Dart block and Dart Pro 1 227 heads.
Have heard 4.165 and others say 4.200.

I use ICS copper head gaskets, with the built in o'ring (sold by good viberation) they are pretty expensive, but i'm running a 1471 on the sm/blk and pushing over 30 lbs boost.
MLS are a lot cheaper but will probably work wit 9 lbs boost, i would opt for the 4.165 size because you need all the seal that you can get.
