Even if you end up with 3/8" push rods, use the stiffest ones you can get. Manton Engineering in Lake Elsinore, CA is one of the premier push rod manufacturers in the business. Once you establish the length and maximum diameter you can fit, they can make them and ship in a week or so. Remember, they can make single and tapered ends for you to fit the tight areas. Again, push rods may be a contributor to your problem, but I think there is something additional going on. Best of luck with that cool engine.

Thank you.
Are yours tapered?

I'll give them a call tomorrow..

I don't think the lifter was bouncing because it looks like new still. Here's a picture..
