Even when the bolts between the 2 are loostened. My question is, can I take the whole thing to a machine shop and have the intake taken down so they are flush? Is there another fix I'm not thinking of? I know I will have the probably have to shave the rings that go between the intake and head too.
thanks in advance

A automotive machine shop can surface your manifolds. The usual procedure would be to bolt them together with a new gasket in the position you want them. Take them to the shop and they are surfaced TOGETHER as a unit. Could there be any other reason that the exhaust manifold won't pull up to the head?

Gooday

Leave the intake/exhaust attaching bolts at the heat riser area slightly loose while the manifolds are being tightened against the head, then tighten these bolts last. You're probably dealing with a badly warped exhaust manifold due to heat.

Probably have that one done too.
I'll let the machine shop guys decide if they want the thing put together or not.
Thanks guys, I get smarter every time I post on this thing!
