    After 5 years of use without issues.. I'd say you are gonna be fine over the long run. High output/high cylinder pressure motors are much less forgiving to guide wear than the lo-po factory stuff.

    I put headers on the 250 six took the head off and machine the top of the intake manifold to adapt an Offenhauser 3 carb intake blocked the center carb and ran the end 2 carbs so 2 one barrel carbs and headers and it eats stock 302s and gets better gas mileage

    Nice! How much power did that mod add to start beating up on those little v8's?

    This is a really useful thread. Back in the late 80s, we had a '72 Comet with a 200 that otherwise ran great but fouled plugs. On road trips, we had to pull and clean the plugs every fuel stop. On a round-trip from San Francisco to New York, we got so good at changing plugs we could do it in under five minutes.
