To answer the OP's question on the copper spray, I've used it on both the mechanical fuel pump, and the oil cooler; both are holding up fine. I mainly did it to hold the gasket material in place. I've also read several posters that have used hair spray; I'd assume for similar purposes.
This thread really interests me as I'd like to eventually turbo my engine, perhaps run a larger pump. That being said, I've paid attention to things many have said. I've read one informative poster state that to re-torque head bolts, and I'd assume studs on existing head, and gaskets(of course without removing the heads), is worthless, as it'll end up crushing the existing head gasket(do to age). I realize in this case, the OP has replaced the head gasket, but I've also read many who've not. Is anyone else familiar with this, and does that mean to install studs, you'll be forced to replace the head gasket, when studding an engine out, or can you simply install studs one at a time, torqued to 127ft/lbs?(without damaging existing head gasket?)......And do you simply torque them to that, and forget about clocking them as the factory did?
Second, I've read numerous poster's state that once removing the heads, that flattening(decking?) of the block, and heads are a necessity almost every time, and that without doing this will lead to premature failure of new head gaskets?
I hope what I wrote is clear, and somewhat concise; I don't mean to be a pain, but it seems a lot of this stuff is a matter of personal preference from what I've read.
