Thanks for the input guys. As I mentioned, I'm not real familiar with the early stuff and actually bought the motor for a parts donor so no worries about Max Wedge origin either way. I did pull the heads tonight and after looking it over a bit closer it looks like someone rebuilt it years ago and never actually ran it. I'm hopeful I can tear it apart and measure everything and if all goes well, throw it back together and beat on it for awhile although that wasn't my plan when I bought it. I'll probably start soaking things to get it freed up for disassembly this weekend and I'll report back with my findings when I do. Thanks again guys! -Trent
