Re: Order/Finding custom head gaskets?
Right, flat surfaces checked by me!
If Fel-pro say's I can use their #1094's on aluminum/cast-iron and both cast-iron, I take it to the bank b/c THEY made them!
And I've installed two .020" thick steel shims on my 11.5 to 1 Cr'd, .060" overbore 409 "W" engine years ago FINE and also hand fit .020" thick, 350 engine shims for installation on my 406 SB fine!
I used good old Permatex, "Indianhead Shellac Gasket Cement" on the 409 "W" engine's stacked headgaskets and dauber bottle, CopperCote on my 406 SB!
And I'm almost anal about retorqung headgaskets at least three time's over as many day's, hot/cold cycling them!!
Darned headers take like 6 or 7 time's to get them TIGHT!!!
