Flat tappet to solid roller...

What does the cam card say for lash?

I didn't read all of the thread so IDK what you have for heads. If they are aluminum set the lash .004-.006 TIGHT and then when warmed up check the hot lash. If it is loose, set the cold lash tighter by that amount. If it's tight by a .002-.003 I'd probably leave it. Thigh term than that set the cold lash a bit looser.


Nice work.

Cam card says 0.022" but no info if hot or cold. Also I am using cast iron 452 ported heads.
This makes me think weather cam manufacturers include thickness change of aluminum heads or not?
I would guess not many people run solid rollers and still use cast iron heads...
I had no 0.022" tool but had one 0.023" size and used that instead. Will check hot lash on weekend.
What values should I get on hot motor? Perhaps I should measure like this only to make sure that all is where it should be at full operating temp?
