Greetings,
I have decided to stick with some honed 83mm liners and "G & H" pistons to cure my leak down ills. I have looked for +.010 rings and can't find any at the big 3/4 or F.W. Thornton. I have not looked at Hastings, Grant, or any other ring manufacturer or a "real" auto parts store. BPNW used to sell them but have none in stock. Does anyone know a source for +.010 rings for an 83mm three-ring piston. I do realize that if my piston to wall clearance and bore measurements are within tolerance, I should be able to use STD 83mm rings.
Q#2 - is everyone still using 30W non-detergent oil with zinc or added ZDDP for break in? Where are you finding it?
Thanks in advance,
