Question on pushrod length and preload

[WE287GN]

well i measured the rods i had and they were what appears to be stock 8.690"
on an 85 turbo riv hot air block,stock 85 shim gaskets and a set of 8445 heads
my biggest right angle guage was too small to measure the preload with the two valves closed(it was a .040" guage)

there was an easy .030" or better between top of plunger and bottom of reataining clip


so if i measured in the correct posistion tdc valves closed, and suposed to measure from top of plunger to bottom of reatainer wire i come up with 2 conclusions

either a: these heads were shaved something awfull,or
b: there is a difference between 85 and (86, 87) as far as distance from lifter to rocker arm(assuming factory gaskets and unshaved heads)

i was kinda hoping i would have come up to short and i could have measured, but now i dont have a guage big enough to measure the preload

any tips or sugestions would be appreciated

thanks

Chris....I am nearly POSITIVE that the distance between the lifter to the rocker arm is the same for all of the Turbo cars.

I had a set of 84/85 Push Rods, and a set of 86/87 Push rods, and they were the same exact length when I layed them all next to eachother.

Factory length is the same on 84-87 TR's.
