Ok well got the block back from machining after waiting a while.  The shop I used told me they could calculate zero desk and square the block.  So assembled the bottom end and I still get FR/R - 0.0010", R/R - 0.013", FR/L - 0.020" and R/L - 0.014" all down in the hole so much for the zero deck.  And its obviously not square either GRRRR.  Well not gonna take it apart to re-do as block is painted and cleaned and such.  Looking for my 292 to be around 9:1 with 0.040 egge pistons.  But now my squish will be over 0.040 with the wanted to use BEST gaskets at 0.047".  But I also came across a set of y-block gaskets that are made in England (stamped on them) also with the #'s AE640 and 1A992.  They are a copper top and bottom layer with some sort of layer material in between.  They measure at 0.035" before install and crush.  The BEST gaskets measure 0.054" before crush.  So these may work better?  Anyone with any experience with these and ideas what there crushed measure would be?

The knowledge on this site is great
