We mocked up our 540 using Clevite 2324P and had .0029 but wanted more so we ordered 119M and that gave us .0033 which is great for our application. Maybe the 2324P would give you the clearance you are looking for (.0004 tighter in our block) The 119M was much tighter on the thrust and we had to work on that to get thrust clearance we needed.

Is this street or strip set up for you?
