Intake question

[Mark Bliss]

I admit to regret for milling a rare vintage manifold to fit with milled heads, when I should have milled the intake face on the heads.
But like many, I was young and knew everything.

Now I am older and know far less... But it is frustrating trying to pry experienced knowledge out of people sometimes.

Seems to be a camp for each side, but I’ve never cut a head before, I always cut the intakes.

I had a chance to run a bore scope down the runners earlier today and as I thought without a gasket the drivers side sat perfect and the passenger side was a little low. The distributor sits pretty centered in the hole. The end rails have about .135 of clearance. Since the intake has been previously cut I'll have .060 taken of the drivers side and .040 off the passenger side.

Had to cut a brand new BBM block to 10.145" once because the decks were that out of whack.

What was out of whack? BBM machined the block with a taper? How much?

The low spot was on the intake side of the deck if I remember right, been a few years back.   It was off about .020".  Had another block that needed a sleeve because of a porous spot.  Had yet another that was porous to the outside of the block leading from an oil gallery.  Nothing like priming the pump and watching oil appear on the outside of the block.  Good times.
