I just installed my new Trickflow heads on my 440. My old pushrods are way to short (9.2"). I have an adjustable pushrod, but it maxes out at 9.8". So I ran the adjuster screw way down to set the lash. With the pushrod at 9.618", the top of the adjuster screw is .089" above the rocker arm. I than back the adjuster screw back to where 1 1/2 threads are showing out the bottom and measured .478". I took .478 - .089 = .389 added that to the 9.618 and I come up with a 10.007 overall length of pushrod needed. Does that seem right for pushrod length? Are the trick flow heads requiring about a .08 longer than stock pushrod? (I know it depends on if block has been decked, etc.)

Also does anyone have the contact number for Smith Bro pushrods, it seems their website is down.
