forget about the summit guy...... sounds like you had it right the way you had it set up the first time. with that said, while you still have the heads off stand the heads on the intake face( where the intake bolts to ) with the exhaust port facing up and fill the exhaust ports with alcohol to above the valve levels. look at the chambers and see if it leaks into the chambers. I would just about bet there is at least 1 bent exhaust valves.
