Default Do I need different pushrods for f13?

I have a tr224 now, and the previous owner just said it has 'hardened pushrods'. Do I need to get different pushrods to run the f13? I was running stock 98 heads before and now i will be running some tsp prc 5.3 2.5r heads (63cc)

the only true answer is maybe, anything else is a guess. You need to measure to find out for sure.

If the heads havent been milled it will be fine with the stock length pushrods.

That is still debatable (preload effect on HP)
The main issue is to run in the .080>.100 preload on the stock lifters. Less will result in a noisier valvetrain.
