Want to stay on pump gas. I mostly ride in FL so I'm just above sea level. Here's my setup:

 

Stock Stroke

Woods Port

T5's

 

I know 21 is ok but what about 20?

 

Forgot to mention I'm running at +4 on my timing.

I would throw the 20's in and see where the motor kicks for comp and run 91-94oct.

 

Im sure you will be fine.
