I'm sorry, but I really don't know anything about go-fast equipment. Try to find a chevy car club and ask them. If you can find one near you, join it and you can have a lot more fun with your car and get a lot of help too. Performance cams usually cause very rough idle, but I don't understand the low vacuum. Some valves are staying open too long.
I know Model A's, not cars like this.
Good luck.
