12 Second N/A Slant 6?

I found it quicker than I thought. Here is what he needed along with the picture explaining the measurement to take. Lemmie tell you, I found this guy SLAM by accident when I was lookin for some hold downs for my 383. He is super to deal with and the quality is outstanding. I'm still gonna get you pics of my head mocked up.

Here's what he said:

"I need:
1. Intake and Exhaust valve lift, minus any lash.
2. Confirmation that your rocker shaft diameter is .875
3. The accurately measured distance between the valve tip and the combination square using the attached photo as a reference. You can hold the square against the valve spring instead of the valve stem. As long as the square is on the same angle as the valve and is resting on the top of the rocker shaft, it will be accurate.
4. The underhead length of your shaft hold down bolts, so I can include the correct length in your kit.

If you have any questions or have trouble properly viewing the photo, let me know and I will respond promptly.
Thanks,
