common problem with 317 heads Just got a call from the machine shop and my 317's were found to have cracks between the valves. Pressure test checked out fine so idk what the deal is. Had my buddy pull a set of 317's off at the junkyard he works at and the 1st set he pulled had cracks between the valves also. He is going to pull another set on monday to see if the same problem is there. The question is has anyone else had/seen this problem?
