Time to get out the triagular file and groove the flat quench areas on the 302's. Polish the chambers

Gasket match the intakes and leave the intake manifold alone so you have a slant anti-reversion effect.

Gasket match the exhaust on the top and sides of the exhaust ports. Not the floors!

My 302's are almost to that point. Just no money for the valve job, and I need toput a new seat put in. where I got too crazy with the die grinder.
