Hey guys, I have some home-ported BV heads (1.625 ex valves 1.84 in), and the the valves are slightly taller than stock.
When I went out to set pre-load, I tried several pushrods: the stock 7.162, some 7.20, and my adjustable pushrod at a length of 7.250.
When I found zero lash, the "thangie" that the pedistal slides on would not seat on the pedistal unless I used the stock 7.162 pushrod. It would seat, but I got less than 1/4 turn preload on the lifter. (what do you call that thangie?)
So I am assuming that I need some shims under the rockers.
Seems I may need some 7.25 -7.3 pushrods, and some shims. Guess I'll find out the pushrod length when I get it shimed...
Does this sound correct?
Thanks!
