318 hydraulic lifter preload.

The shop that rebuilt the heads is a well known So. Cal. machine shop with 40 yrs in business. I'm not going to bad mouth them unless it's warranted, they are helping me out and I'm probably the PITA customer. :violent1:

I spoke to them and they are going to surface the head -.020, no charge. I didn't demand anything, they offered without me having to ask. I would have paid the surfacing charge and had no problem with it.

However, IMO, the valves are not where they should be. "But", I can only prove that by installing all new components or measuring them myself, which I do not have the tools to do so, and buying all new rockers and shaft is not what I want to do.

Plan of action is: Document all the clearances, get the heads checked and milled .020. Hopefully be able to use the new stock length push rods, ( 7.500). Re-check lifter pre load. At this point I should not have to do anything further with the valves/lifters. But if so, I do have 4 brand new push rods that are .030 longer 7.530, I couldn't source a full set of .030 over push rods. :???:

I'll post up the clearances when I get it documented.

What will be the compression ratio? Stock pistons, felpro gasket and -.020 milled head.
