There is a non jet head on ebay with a stripped exhaust stud cheap right now. The Balance shaft kit is not much more than a stock timing setup, I'd do that for sure. The ARP head stud kit is pricey at $90 but it gets rid of the second design flaw for longevity, the stretching head bolts. I also say rering with a good hone and spend the difference on a non jet head and bs elim kit.
