Hi J, the best position we've found is just outside the 2 end head bolts, we use SBC timing cover dowel pins (.250"). One or two will hit water so we seal the pins just as a precaution even though the press-fit won't allow a leak.

We use our honing plate as the template to locate the holes. We drill the block holes with a letter "D" drill and the head and gasket holes .250".

Began doing this procedure about 20 years or so back!

Thanks, Gary in N.Y.

P.S. Wishing all here a very Happy New Year!
