Help with 340 compression + cam change

Have decided to try the 650 AVS2, the size of the primaries is right between those of the smaller and larger TQ’s.

And for now this cam stays. It’s working fairly well. But I am interested in optimizing what I have.

I was actually going to ask advice about the possibility of advancing the current cam a few degrees?? (Since I need to install a new timing cover anyway.)

Would this maybe build more cylinder pressure? If the torque curve moved down a bit I’d be fine with that.

Wyrmrider, I’m not sure what you were saying in regards to 1.6 roller rockers. Were you advising against? (I do understand the necessity of getting the geometry correct if used, and saw info on the B3 Kit.)

Again, I really appreciate the advice, I continue to learn a lot as I work through these possibilities.
