Diagnostic question

I would think the leak down would be worse with bent valves would it not?
Are you running stock push rods? If so you said they are straight and not bent?
Cant remember ever bending a valve and not bending a stock tube style push rod
If your going to do a compression test pay attention to the first bump 75 , 85 , 100 or whatever the number is and the following 3 or 4 afterwards , record those #s as it will tell you something.

Depends on how bent they are. Here’s a good one that some guys don’t think of.

I’ve seen valves so bent you’d think they wouldn’t seal, but if you put enough spring load on them, they will seal up.

So it’s possible your valves are bent a bit, but even 120 pounds of seat old can partially seal up a bent valve.

That’s just an FYI because I’ve seen it many times.
