Intake perfect fit without gaskets.
I went back to my shop just now and threaded in four bolts semi tight, with no gasket. All the bolts go in easily. I looked inside with a cheap Harbor Freight bore camera and saw no problems with alignment. The head has been gasket matched, but not the intake as yet so all I could tell is that there is no ledge going into the head. The angles of the faces of the head and intake are spot on. There were only two places around the perimeter where there is any gap at all. Couldn’t find my feeler gauges at the moment so I stuck a putty knife in, 0.023 inches thick. Pics attached. The intake fits perfectly at the back. The two gaps are one side of the front china wall and the opposite side top of intake. I think if I do machine it the geometry is okay so simple cuts only.
