Just wanted to thank everyone for your help! I just got the push rods today from Summit. 7.550 did the trick. Super quiet and smooth now! That's amazing what a difference that small amount of length made!
I'm not running it anymore. Hopefully I didn't already damage them. It's a crane cam i installed 3 year's ago. It was new then. Just swapped to different heads this time. Same cam that I already had in it. 454 lift
Thanks for your help guys. I was looking at that exact size push rod online last night. 7.550 I think you are right it is just sitting on top of lifter and not depressing it at all. No up and down play just looks like exact size without depressing it at all. Hopefully I didn't ruin my lifters by...

Swapped heads on a 73 dodge dart 318 went from stock heads to a set of 302 castings with 1.88 stainless valves. Engine runs great but now has a lot of lifter clatter and it didn't have it with the stock heads. Any suggestions on why?
