Running the same heads etc, it would give you a higher comp. ratio too.  Different heads have a different chamber cc.  Something to consider.  At a guess, the 395 wouldn't be ideal as there would be more angle in the rods and more wear on the piston sides.  It'd also rev a little slower but would give out a little more torque.  Definitely more clearancing, so I don't know if that affects the blocks structural integrity.  If they were the hot sauce, everyone would be building them instead of the 383 I guess.

You are not going to running stock heads in any form on a 396 if you want it to work. Aftermarket 195's at minimum; 205- 210 if wanting to make full power

It is the "iffy " factor; too much chance of hitting the water jackets while grinding with core shift ,etc. 3.750 stroke seldom has this problem.

Exactly ; get a late 1 pce seal block for the build. Roller cam is the ticket and a factory roller block saves you $800 on a set of retro fit roller lifters.
