A boys first broken pushrod.... LOL

Their response was that those were the only ones they could get for adjustable rockers. I've lost what ever faith I had in them today after talking to them.

I have a set push rods that are shorter. Not a huge amount, butt the amount they are shorter, would give more clearance at the rocker.

I will go measure one of each.

You can get pushrods in ANY length you want, with whichever style and size ends you want. Any engine builder should know that - and custom pushrods really are not that expensive in the grand scheme of things.
