After running my car hard I noticed it was misfiring so I replaced the plugs and it is still the same. Was told I might have a bent valve. Im having the shop do a compression test before removing the heads. Anyone have any ideas what the problem could be?

Plug wire, injector, and fuel filter would be good places to start before pulling the heads.

I would check the coil pack to the side miss firing.

Too many things to check before you go ripping the heads off and possibly find nothing wrong with them.
