Anybody ever heard of needing to put in shims after you shave your head down? If so how do you do it? I had my head resurfaced last year and put all new timing chain in and everything and now my chain skipped a tooth and then later stripped off all of the teeth on the sprocket. and when I went to get a new timing chain set, checker said I needed shims and I don't know how to install them or where, and checker didn't carry shims and I have to go to another shop, like a machine shop to get them.
what your checker dude was referring to was a head gasket shim, do you remember how much your machine shop took off the head when it was shaved??
also was your timing chain tight when it was installed new??
