Can someone help me get an idea of what pushrod length to get for my current setup? I have a 5.3 with a set of 862 that been ported and polished and have been cut .20. I also got some felpro headgasket with the compression thickness of .41 like .10 less than the oem gasket. What would my pushrods end up being? Thanks,

You need to buy a pushrod length checker, that is the correct way to find the right size pushrod. That's not something you wanna guess on.

Yea buy the tool and measure it. Don't forget to add the preload on top. There is a youtube video by Katech and summarizes the process pretty well.

This is the only correct answer.

Measure it as said,

But you won’t. If you guess at it, 7.375 - .030, gets you 7.345, which you probably won’t find so 7.350’s.
