Helping a friend put together his 383 and we are just about done, but he isnt sure what head gasket to use. He has a ls1 stroked to a 383. I assumed the bore is the same as stock since it was only honed? I am right? Would it use i guess a stock GM MLS gasket? He intends to run some boost between 15-20 lbs i believe. Let me know what gaskets it needs so we can order them already.

Thanks.

so a 3.910? What about a 3.905? which would be better for him. Trying to help him get his car on the road so I can be done helping on this project.

With those heads and that boost level, the GM MLS gaskets will be fine. You will need 2 of PN 12589226. We have them here: http://www.thunderracing.com/catalog...&sid=353#P2438

Yes it is, the bore size on those gaskets are more than adequate for both your heads and block.
