Re: Sealing SBC Head Bolts
Thanks for all reply's. What I am seeing is the same stuff still works..... . And, no really new super secret stuff, which is fine. Going to use my same ol' permatex thread sealant, and be happy !
If life was easy I would be bored. My EX-Wife has assured me I will never be bored.

Back again.................
Old-fashion "Indianhead" for the win here.
Spend your money on the high-priced stuff, but after it all said and done, Indianhead as cheap as it is, does the job like it was made to do!!
Thickly daub the threads and put a schosh under the head and go!! Messy crap BUT it works great by me.............

And, do you change it up when head bolts are going into wet blocks using some Heli-coils? SBC 010 block from 72......... Just wondering. Going to be setting some heads down on a block this weak. I know what I used 20 years ago, wondering if there is anything new now that is any better than permatex sealant?
Same hear.

I just use Permatex thread sealant, never have leaks.
Heli-coils will cause issues though no matter what sealant you use, highly recommend changing them out for Time-serts.
