Probably just a couple of bad valves. I have had bad luck lately with Manley SS exhaust valves. I have had 2 exhaust valves drop the heads off and destroy 2 good engines in the past couple of years. The last set only had about 75 runs on then. These are small diameter valves too. I guess I will start to change the valves at 50 runs from now on. The Manley stuff does not seem to be as good as it used to be.
