Push Rod sourcing problems

[Dads 64 Valiant]

Hello all, it has been a while, little back story, inherited my Dads 64 Valiant 225 six V200 (actually his dads car) and started to get it running well enough to ship it from Ontario to Calgary by train, on start up found three valves seized, sent head out to a racing engine machine shop( they said they were very busy, 14 months later, I'm putting it back together. I ordered three new push rods to replace bent ones from Rock auto, Melling MPR-152, they arrived today, the ball end is 20 thousands larger than original stock and about 30 thou shorter, any suggestion what and how to get the wright ones would be great.
Thank You
Kevin

I'd put a want ad for 3 or 4 originals. Rock Auto stinks for early A-Bodies. Not much is correct.

I’m not sure if the /6 lifters ever came with two different seat sizes in the lifters. I know the V8 stuff did.

Wait a minute. They are all the same. So now that my head is out of my butt you can use the bigger radius ball in either lifter.

You can use the small radius ball in the big radius lifter but the issue is if the pushrod slides down the seat and ends up on the edge of the lifter.

If that happens and you don’t catch it, you can bend valves. BTDT.

I’d use them.
