The Ford Barn - View Single Post - 21 stud deck height, gasket thickness, etc. questions.

Thanks Frank. I can't read much on that print, but I do see the 10.437 deck height.

I'm making an assumption about the the piston compression height by assuming the pistons I have are close to nominal, since they are all the same within .005. Are there any prints in existence for those pistons, to know what they are intended to be from Ford?

Cutting the deck to 10.437 and making the stroke 3.7500 would still leave my pistons .036 below the block deck.
Adding .020 to the stroke would still make it .026.

Looks like without custom pistons the fix is to profile the heads. At least I can do that here.
How deep can I make valve reliefs in stock ford heads?
