Ok, I have cleaned up three sets of intake exhaust manifolds and just snugged them together and the exhaust are warped. its the inner exhaust ports that seem to be the worst. 020 to 030, I don't believe the intake can be milled that much. Trying my best to put this truck back together as stock as possible. I started with an offy and 2 carbs, Fenton headers and shot gun exhaust. looked great but I could not solve the leaking under the intake. I also heard That a triple will run and behave better. I have a new triple offy with three W1 carbs professionally restored with the correct metering rods for this set. Then I am back to trying to heat the manifold. How far can have the GM intake exhaust milled before I get in trouble? Looking for some help on this one. Or whats the answer to heating the intake. I have read and understand why the manifold needs heat per the shop manual. The Triple would look cool.
