Head gasket's?
 

Hey guy's what is the stock size head gasket on the LS1 motor's? I need to get a set for my build looking for a MLS set to handle the spray. Thanks.

anything from 3.903 - 3.910 will work.
I believe the stock thickness is .053"

Ok thank you. Yea i was on tsp last night and they have like 15 different kinds on there site lol.

either run cometic or gm mls gaskets, iam running the gm mls gasket on my 347 ls1 with no probs, soon to be spraying...
