Hello,

I'm having a set of "C" heads redone. They've been milled .030". I'm having hardened seats and new stainless valves installed. My question is, what is the height the top of the valve needs to be above the spring base so I have the correct lifter preload? I probably did not use the correct terms but hopefully you know what I mean!

Thanks.

I am not sure of the height as a measurement, but some years back I bought a gauge to check this and have since used it on all the heads I have done. Give Dick Miller of dick Miller Racing a call and he can sell you the gauge and you can give it to your machinest to use. Dick can also give you advice on the proper way to adjust the height as opposed to just grinding off the tips of the valve stems.
Good luck.

Hi,

I'm no expert by any stretch but I've had some great advice along the way on this particular subject. Unless you go to an adjustable set up, definately invest in the valve stem height gauge. It's a must and a lot machine shops won't have a clue how to set them up without it. Mondello also sells one and it is worth it's weight in gold even if you only use it once. The instructions are really simple as it's a go-no go gauge with itiot proof instructions. I learned from experiance!

Thanks for the help guys, I have a gauge coming from Mondello.
