For today's project I finished tearing everything down and inspected the heads
and some smaller parts. I discovered that only 4 of my pushrods were perfect,
4 were marginal, and the other 8 were definately bent. I also discovered that
I showed signs of valves hitting the pistons in all 8 cyls. At least 5 valves
are visibly bent. All of the installed heights of the valve springs are
roughly correct but the tops of the valves are all at different heights, seems
the spring seats are all at different heights by 30 thou or so. I also
discovered that all of my valves are slightly oversized, by .019 on the intake
and .034 on the exhaust. I looked up the head casting numbers and found they
were 43cc chambers but only got 40cc when I cc'd them. On the left bank I had
one .020 thick head gasket, on the right bank I had two gaskets totaling .035
thick. I think they were the new ones but were stuck together and got
installed together. I don't think any of this caused my problems, but I do
think it would have caused them later had the rod not broken, who knows at this
point. I do know that the rebuild seemed to be half assed, and was a time bomb
waiting to explode.James Nazarian71 B tourer71 BGTV8 with ventilated block and
