IF you decide to deck the block, for every .010 off the deck, cut .0144 off the front and rear block rails (often over looked when block is decked alot). This is from the MP engine book, 1982 edition. Then check distriburer engagement in the dis/oil pump drive, you don't want to bottom out hard.
Good luck,

One way you can get around that is to eliminate the use of the cork end gaskets and just use RTV. I started doing that over 20 yrs. ago and love it. No more problems with end gasket leaks.
True enough, that is excatly what I did; however between the deck cut to 9.580 and the cut on my Eddies to get a 60cc chamber, my intake bottomed out on the end rails anyhow. RTV so thin it was transparent.
Just one of those things to keep in mind.
