Valves

I checked the lenghts of the valves.
I had a valve/guide from another engine ( std Ford ) and lengts of that valve was = 4.80".
I had the cam in block and did lathe small bearings in aluminium.
The cam is a cast Potvin 425 E based out of a 8AB
and basecircle of that cam is D= 0.8854".
I guess way smaller than a std Ford cam.
The lifter I like to use ( I did find a NOS set at 47 grams, guess std 8AB or? ) and height of that lifter is = 1.7445".
Se picture of how far that lifter is down in the lifter hole and against the base circle.

So I installed the valve and it had a gap of 0.1299".
Valve clearance should be on intake = 0.013".
So that get me a valve lengts at 4.9169".

I guess that is pretty equal from what a CSB is, and I will stay at 1.5" valves.

Now, I has not make new seats and I has no idea how the base circle will be on my 32 cam I plan to use and after it's been grinded to the 425 E profile.
So this is just ruff for a test to see where it all leads.

Has anyone ideas on this and if I go Manlys what does those valve weight ?

And as I plan make my own guides, I can go 8 mm stems aswell and not CSB std stems.
But I has not look what is out there.
