Head gasket sealer

[93gc40]

I use a Felpro and NEW bolts to seal my Heads.

i've never used the copper spray on a head gasket, though i have used it on the 4.0 intake/ex gasket a couple times with great success. i used to work by a place that did import performance stuff, turbo's, head swaps, vtec things, etc. the guy there swore by the copper stuff for use on head gaskets, he used it religiously.

ya ive been hearin alot of good things about this copper stuff im gonna invest in some to keep in my box.... felpro head gaskets are dry application but if my intake/exhuast start to leak i no where to turn and ya i also used new head bolts didnt want to take a chance on the old ones
