No . Install the head gasket clean and dry on a clean dry oil free block deck and head.
Clean the gasket block and head with laquer thinners to get the oil off.
Leave all the sealer crap in the tool box.
Retorque the head bolts afer a few heat cycles.
You can put a small amount of Black Permatex sealer on the threads of the head bolts and under the head of the bolt.
Use it on the exhaust rocker studs if you have screw in studs.
Use a small amount on the clean dry oil free block china walls and around the water port holes only on the intake gasket. Thats all.
If the head and block are reasonably flat the gasket will seal fine.
If the head is warped no amount of gasket sealer crap will make it better.
They either seal or they don't.
If you want to do something good chase the threads in the block with a tap and buy new GMPP cylinder head bolts. best $20 you can spend.
I have never had a shim gasket fail in 35+ years of using them on SBC's and BBC's
(even with nitrous)
