Help needed. Just did my first cam swap. BTR stage 4. New rockers, valve springs, push rods, lifters, timing chain, cam sprocket, and oil pump. I got an extremely loud squeal and chirping sound after first start up. Ran it for maybe 2 minutes all together and has only gotten worse. It’s definitely in the top end. Anything I may have missed or other rookie mistakes??
