Very interesting....
I did try & call but, no answer. I assumed you all take the weekends off.
I have the Erson shaft with END STANDS (thank you Ford) !
and 1.76 roller rockers.
I'll sell my heads, they are ported to the max.(I'll have to look at my file for the flow #)
This is my engine now. Although I sanded my block smooth and painted it and the heads my body color, with the aluminum block & heads, I would hate to cover them up with paint.
(I have replaced the valve covers with pentroofs)
