The head bolt holes on the Y block are ‘blind’ holes which do not require sealer on the head bolts by lieu of no water at the threads. But oil on the threads is still recommended for proper torque.

I would use sealer on the head bolts that go in to the water jacket.

I have a can of Permatex copper head gasket spray, what do you think about this stuff, is it equal to the K&W brand or is K&W better?Should be the same or close enough that there's no difference.

Assuming you’re asking about head gasket sealer and not sealer for the freeze plugs themselves, then if using the Best Gasket brand of head gaskets, they can go either way, sealer or not but if using sealer on these then use the spray on K&W Copper Coat. And don’t use RTV or 3M cement on any head gaskets period. Yes, I’ve seen that.I have a can of Permatex copper head gasket spray, what do you think about this stuff, is it equal to the K&W brand or is K&W better?

You won't need sealer on the head bolts. Use oil or assembly lube. The torque specs are usually different depending on the type of lube used. For instance, ARP has a reference chart for torque specs when their lube is used. I think most factory repair manual torque specs are based on using a certain viscosity of motor oil.

thanks, Tim... ordered mine yesterday from CC Parts in NV... man, have they gotten my $$ as this project has unfolded!! how about the thread sealer question on the head bolts... seems there is some difference of opinion... in my case, I am using the original ones, not replacement/upgraded ones... target date for this work is in the next week or two; appreciate all the input and insight so far!

Oh, wait, I was talking about the intake gasket. I thought for sure I had read intake gaskets.

I apply a skim coat of silicon to the coolant passage part of the gasket and leave the rest dry.This works wellas long as the gasket surfaces are flat and smooth. Also, use thread sealant on the bolts and studs.I'm interested in further discussion re: the subject of using thread sealer on head bolts, and possible interaction concerning recommended assembly lubes/torque specs.?
