But, I was thinking the low vacuum was most likely from the cam. Any thoughts or ideas?

Also, I have no idea what pistons are in the motor. Everything has been a surprise so far. Thanks!
I hate when people hog the port opening out thinking they will get more air flow, what you can do is buy a felpro 106 gasket and glue it to the port with the yellow sealer, then trim the gasket and use some sealer on the intake and let it dry for 24 hours. The area at the top of the port is just the valve cover stud, I always epoxy them in and smooth them over with the sanding roll. If they are not cracked and seeping water in the ports or oil run'em.
