The 396 is missing a little after some spirited driving on Sunday and I suspect a valve problem. I went to do a compression test yesterday and found out my compression tester won't fit into the tapered seat plugs on the heads on the engine(1971 oval port heads). So I need a compression tester for the narrower thread design and the threaded portion will need to be pretty deep just get in far enough to engage the threads. If somebody has one I can borrow, let me know. Thanks!
