I had an M1 intake on my 383 when I first built it. sealed up just fine. swapped over to the performer rpm intake and it was sucking oil from the lifter valley. I then swapped heads to the trick flow's and the intake leaked with those heads also. after a bit of investigation i have come to the conclusion that the intake was milled incorrectly.
you can see in the last picture that the top of the crush bead is flat and on the bottom of the port the bead is virtually untouched.
I will also mention that the deck has never been cut on this block, the heads are not milled and i am using a standard .039 crushed thickness gasket.
