I read somewhere that the pushrods are the weakest link in the valvetrain, 120 for hardend is cheap insurance in my eyes.

Not only that, when you are in the process of replacing vavle springs, the pushrods are fully exposed. All you have to do is pull the old rod out and drop the new one in - takes about 34.7 seconds for all eight once the rocker arms are off.

Hmm, you must be slow. Ive heard of all eight rods being swapped in only 32.6 secs. You need to practice more, broj/k
I figured this would be the right time to do it, since youve got the valve covers off. I just didnt know what the real world experience was with the stockers. Ive heard that they were kinda weak, but you know how people find a way to make the oem stuff last with some tricks. I guess these are just so easy to replace that its a no brainer
Yeah, I wouldn't chance bending a pushrod. My friend just ripped his engine apart and i believe it was the number 3 cylinder that had a pushrod do a contortionist act. It was pretty gnarly, then again he has a FORD. Oh, and I'll work on getting faster - maybe I can get faster than 33.9 seconds
