Someone will pop in with the answer I'm sure. I will try to talk you out of decking the block a huge amount. A few thou. to clean and straighten it up is good. If you shave a lot the heads and intake won't fit right and will have to be machined also. Those heads and intake will always have to be used with that block. You can also have problems with pushrod length and head bolt length too.
The correct pistons are the way to go. tmm
