I used Fel-Pro on mine. I took the exhaust manifolds off, wire wheeled them.I scraped off crusty crap from the block w/ a good sharp chisle.
I then installed them back on w/ all the bolt and left about a 3/8" gap between block and maniflod.I slipped the new gaskets in and torqued the bolts down,The Fel-Pro gaskets do not have bolt holes to fight while lineing every thing else up. They are hook shape at each end to hang'em on the bolts.Oh yes,a good can of penatrating oil will be your best friend, soak'em then wait 10min or so,then soak'em down agian.
