When your cranking compression is that high, you will need to pull a few degrees of total timing out of it, unless you are running high octane fuel. I'd put thicker head gaskets on it next time you have it apart. My opinion, of course
The next time I have those heads off I'm going for way bigger head gaskets as I'll probably have closed chamber heads.
I'm hoping somebody with some nice Edelbrock heads gets trick flow fever...
