Ok so this is probably a dumb question but here gos... My machine shop doesn't shim my valves after a valve job so it's up to me to handle that. What I've been doing is just sitting down with my shim kit and just swapping out shims trial and error style till I get my desired clearance. Is there a better/faster way I can do this??? Perhaps throwing the buckets on without shims, getting a clearance and doing some math formula???
