Felpro heads copper shim

[Nacho-RT74]

I wouldn't use copper unless the block was o-ring'd....asking for trouble. 

Mancini has the proper .020 steel shim gaskets in a 4.40 bore diameter for your 400 stroker and they're cheap. 

Do it right the first time !

At the end got them, because was found the block has to be cut to 0.040 overbore.

So another block has to be obtained?

yes, and is already at machine shop. US$170 for the block

pistons will be KB251s this time... cheaper and step quench can be matched with the asemmbly instead the other way around
