set the milled heads down on the block with your choice of head gaskets & hold the heads in place with several lightly snugged head bolts then set the intake/intake gaskets on & note the actual distance along the slope that is misaligned. SB intake faces ain't exactly 45 degrees to the deck so give your measurements to him & let him do the math & give him back the heads for the intake faces of the heads to be milled. Toss the front/rear cork gaskets & use clear silicone as they can be too thick stock & after milling definitely will be & can cause a front water port leak. If the intake sets too low search for some thicker intake gaskets.

When an engine is zero decked, say a magnum 318, does the intake manifold also need to be modified?
According to "Mopar Speed Secrets, 9th edition", an 850 page Mopar Performance Parts publication written by a Chrysler racing engineer in support of the hobby ($10 at http://chucker54.stores.yahoo.net/mo9thedensps1.html ):
"The 'A" engine block... The intake manifold surface on the head should be milled 0.0095" for each 0.010" milled off the gasket surface of the block or heads. Since the intake manifold also seals the top of the block, the front and rear block rails will have to be milled 0.0144" for each 0.010" milled from the head and/or block deck surface."
This book is well worth the ten bucks if you are restoring or modifying any Mopar engine. There's also another similar book named "Magnum Engines, 2nd edition" for $10, 450 pages. Mopar "Chassis" book, 448 pages, is also a good buy at same price.
Interesting what the author had to say about Ford's and GM's attempts to support racing, compared to Mopar's.
BTW, you can sell these books on ebay for $10, when you are finished with them.
