I never have chatted on forums before, but I need to cool off a bit & would like to find an answer to my question.
I've been working on a 1973 Runabout w/ a 2000cc 4spd (it was my daily driver). I had the head "rebuilt" 5K ago.
After removing it & finding multiple cracks (had coolant in the cyl.s & oil) I decided to use its valvetrain on another head after checking the guides, grinding the seats & doing all the other necessary work; making a long story short, all the valves were un-useable(stems well worn out of spec., a few were bent- among other things), the followers from both heads needed replacement, both sets of springs were worn out, and both cams were worn out (journals & lobes on the one out of the "rebuilt" head/lobes only on the other one).
I got all the needed machine work done at a local shop & I'm going to use a vernier cam sprocket. I ordered the following parts from Burton Power: Kent FR30 cam, followers & performance valve springs (75lbs@1.500") for lifts over .460". They sent me the wrong springs, so I'm doing other work while I wait to hear back from them.
In my "free time" I've looked for the valve stem installed height specs, but I haven't had any luck finding them. The only suggestions I've found are to use dykem, assemble, grind & repeat as needed. I've also been told to "put it together & run it." The first suggestion will be very time-consuming, & the 2nd wouldn't be prudent because it wouldn't be possible to accurately degree-in the cam & have the timing consistent at each cylinder(mechanical lash adjusters).
If I had the factory stem height specs it would save a lot of time & aggravation. Any help is greatly appreciated. Thanks!
