Correct Pushrod Length

When I install my AFR 165 heads I want to be sure I use the correct length pushrod, does anyone know which tool I need to use to measure this and where I should go about buying it? Also any help with the actual procedure would be awesome. Thanks in advance!

RE: Correct Pushrod Length

Check this procedure on the valve train geometry, you could also "build" your own adjustable pushrod....

Take an old pushrod and cut it about 1 to 1.5 inches from either end. Now use a 1/4"-20 tap and tap both open ends, then simply screw in a short piece of 1/4 inch threaded rod with a few jam nuts and voila, you just saved 20+ dollars and 3-4 days on shipping time.

RE: Correct Pushrod Length

Yep, get or make an adjustable pushrod. Set it up so you roller tip sweeps a pattern that's centered on the valve tip. No big deal. Make sure you measure the length the way the manufacturer of where you plan to buy your rods from does.

I think you can find an all explaining article on the Comp Cams website.
