Car doesn't want to rev!

Could slightly bent valves cause a problem like this? I bought the head used and everything looked fine. I'm still going to do all of the other things on my checklist, but it's starting to look like it could be the head. The car smokes alot and backfires frequently - the smoke is grey. Now I am going to do a compression check as well.

different ecu fixed the reving issue. Smoke didn't go away. Decided to take it around the block - wouldn't boost and it died right before I got into my driveway. It seemed like a clean kill. Haven't determined what happened yet.

Good job on fixing the revving. Now you can't make boost, and you're still smoking. Hmm I guess I know what I'd be checking next!

I'd do compression and a boost leak tests.
