Help! 360 with 302 heads no compression

This is what it looked like when I first took it apart. It had 4 bent pushrods. The heads were so gunked up with lacquer and carbon that i have to tap out the valves with a hammer. Once cleaned I saw the heads all have cracks between the valves. Its a 92 dodge truck that is a roller motor with non roller rockers. I had a set of 302 heads that are fresh. I put them on and get regular la push rods. I didnt know there was a difference between the lengths. I only had built older la motors before.

.That has roller lifters in it.
Go to oreillys an get pushrods for a 92 360.
If your lucky you didn't bend any valves but you probably did.
