I have , the 56K original mile 383 HP in my dart , it still has shim head gaskets with part number begining with 18 part number , the pistons are if i remember right .006 in the hole , should be .003 , I haven't cc'd a head yet ...
So you'll telling me they only missed by .003... That would be exceptionally close to spec... Are you sure you didn't add a zero??? Cause .030 wouldn't really surprise me... .080 wouldn't eiither...
