Hi,
Where I was going with the query was this: I had a late block "decked" with the
intent of making the deck flat. The machinist took of .032 to accomplish the
goal. With a head gasket installed and the head torqued, the clearance in the
squish area is .030.I had initially wanted only about .025 removed, but we had
to shave an extra .007 to get rid of the fire ring cuts.On initial startup, the
motor sounded like it might be "rattling" and I'm trying to figure out why.When
I used a stethescope on the block, everything sounds okay - no rapping and the
valve train sounds "normal" and there were no weird sounds coming from the
crank.I guess where I'm going with this is: if piston / head clearance is too
tight, I'll see some sort of indication on the piston, right?TIA for any sage
advice.This is my first experience "decking" a block. I'd like to get it right,
I don't have the resources to start a new block from scratch.Regards,Bob Lang
