Magnum Heads On 340

Thanks I did catch the interference between the head and manifold and ground down the head.
Using a flange was something I thought about too.
A magnum flange with extra meat around it to catch the LA manifold but I wouldn't want it to be very thick. Maybe 3/16" would be about right.
If someone had a CNC they could cut some that would bolt on and fix this problem.

SendCutSend can cut stuff for you. I have a pattern I gave someone here recently for this exact reason.

Can't promise it is a perfect fix, I have the same problem (Magnum R/T heads with 340 manifolds) and my adapter plates seem to be ok. But I have leaks I haven't identified so it could be them.

I think I used 14 or 16ga plate for mine, I didn't want to push the manifolds out too far.
