You really need to find out who the cam grinder is and talk to them. That being said there are some very tight lash cams that have been produced for a very long time now. 50 + years ago I had a cam that called for 0.010" on the intake Hot.

You can talk to your cam manufacturer and ask plus you can play with it a little. I used .005 with my LT1 when I was running shimmed lifters and it really liked it. Coincidentally, I run exactly the same lash with my solid rollers now and same camshaft.

We must have shimmed the **** out of the old lifters.

First thing you need to do so is, if the mystery engine builder can't tell you, if it's indeed solid lifter. If it is, 5 th o u sounds about right. You need some Lash but don't want to give up much lift if you can help it.
