I agree...Those manifolds are also total pieces of casting nightmare *****.
The port windows are a mess all of them are too low.

Now the Hughes you post a link to, that's a nice piece

I just bought a Magnum crate engine (300hp) from a dyno shop local to me. Going from a stock cam to a small comp (212/218 .480 114) and switching from an M1 dual plane to an RPM Air gap, the thing picked up 65hp and lost no torque anywhere.
