I've always thrown the white gaskets in the trash. I only use FelPro blues and retighten after two heat cycles then retighten over a few months a few more times and good to go. No locks needed. Should retighten the intake a few times as well.I put Black Jack headers on my 69, 350 ci. Plugs are easy to get to, straight plugs, but use GOOD gaskets! Stay away from the junky white Mr. Gasket junk. They'll blow out in 1 summer.
I put on a set of Pro-form, and the store owner said if they ever fail, bring them back and he'll replace them for free. That was in 1995, they're still on the car.I've always thrown the white gaskets in the trash.

Longest I've had FelPro's is 6 years as that is the longest I have kept a car for.I put on a set of Pro-form, and the store owner said if they ever fail, bring them back and he'll replace them for free. That was in 1995, they're still on the car.
Come to think of it, it could have been Fel-Pro OR Pro-Form, can't remember which one it's been so long ago..I've had my Nova since 1991, it came from N. Carolina, and it still only has about 67k miles on her.Longest I've had FelPro's is 6 years as that is the longest I have kept a car for.
