Re: New Snyders head
I use a 5.9 Snyder's head and smoothed the combustion chambers with an air grinder to eliminate the potential hot spots as in an earlier post.
I also set the head on my bare block with out a head gasket and it rocked back & forth! It was warped several thousandths & had to be milled. Snyder's offered to ship another head but the first on took three weeks to arrive. After talking to them I had the head milled & sent them the bill and was reimbursed.
I had heard many suppliers machine green castings and they will move around after machining is initially done.
