Thread: Head gasket for o-rings

Usually the block gets o-ringed and the heads are receiver grooved. Check the depth of the o-ring and if possible, surface them and use cometics. If not feasible, use the Flatout rubber coated copper gaskets ..

go with SCE....

I run o-ringed heads with cometic MLS gaskets and no receiver grooves in the block. Seems to work pretty well. Why do you want to run o-ringed heads? Are you having a problem lifting them or pushing coolant?

I am now buying the short block they came off of. The machine shop said I would be better off getting a special gasket for it ...

Yeah, o-rings really aren't typically needed for these engines like they are for Gen III/IV V8's and the Buick V6's due to them lacking a head bolt per cyliner. Unless you're going to be running crazy boost though.
