checking valve clearance

[QuantumMotorsports]

Thanks for the help guys. I think I've got something kinda weird going on because my pushrods are 6.9 inch (which is stock 76 302 pushrod length, for the flat tappet hydraulic) they are too short by about a quarter inch with the gt40p heads and the stamped steel stock rockers. My adjustable rockers that I'm getting have an adjustable pushrod seat (Angus Racing Rollers) and they say that they adjust up to a half inch. I just need to get the rockers and get them bolted on to see what I need to do I guess. With the half inch of adjustment in the pushrod seat in the rocker Maybe everything will be fine. I guess after thinking about it with the pedestal mount rockers with adjustable pushrod seat the length of pushrod doesn't have any effect on the geometry of the rocker. The pivot stays the same so the valve wear pattern can't be changed. Anyway, thanks for the help guys. I'll let you know how it turns out.
