I have done cams on quite a few B2200's going back to the 90's - all from the same guy - Shadbolt cams in vancouver BC
He has a couple of excellent cams for these motors and with just cam and headers on a stock truck it makes a huge difference, I have never like that when porting heads you lose torque almost every time in these motors.
If doing a cam, it is a good time to do the solid lifter mod too.
Anyone who needs more info can feel free to PM me and I can help you contact them.
