Manifold surfacing

Posted by Dave Munger On 2014/3/1 18:50:32
Has anyone faced the intake & exhaust manifolds for a 282" engine after they have been reporcelinized? The intake has been on the car forever, the exhaust was something newer & non-porcelin.
They fit & align quite well, but flange surface to the block leaks when they are installed, as much as3/16" when
they are bolted together. I think they should be bolted together and then surfaced until true.
Thanks for any ideas / input.
