In Brief:

I had bent some valves and had the head fixed, compression tested 100%.
I recently got the car back and heres the problem:
When I accelerate, the car runs fine and completely normal under 3 rpms, I can even go higher all the way up to 6 or 7 if i lightly tap on the accelerator. But when I spool or casually go over 3 rpms, the car gets all hesitated and restricted to gain rpms or speed. It will slowly try to gain speed and i get like a pulling back kind of feel. Whats everyones say on this...

is the timing off or the cat clogged
