Burned Valve question

So I was street tuning my car, and I after I tuned my maf and VE table, I forgot to to PE back on. I took it to redline about 3-4 times...and didn't see any KR or anything.

Well this morning I was tweaking the tune, and realized what I did...

Anyways, car wouldn't start for crap this morning, just kept dieing on me. After it warmed up, it ran fine, but now it ticks. Here is a video.

Can you burn a valve with 3-4 quick accelerations?

I'll try to pin down where its coming from. Just a 228r cam, new valve springs, and lt headers with off road pipes.

That sucks, why did you turn PE off??? You can filter it out of your histograms

lol, I didn't even know it could be filtered out...I'm new to tuning and was just following some "how to's I found. they were written well...I just got a little ahead of myself.

Just from a quick listen to you video it sounds like a lifter tick, but I really dont know. If I were you I would try to isolate the sound to left or right side, top or bottom of the engine. If its up top pull the valve covers and remove all the Pushrods and see if any are bent.
