Back in September I reported that I had was overheating at the SCCA
double race at the Glen. I had wild fluctuations in the temperature.
I finally got around to tearing the engine down and found 6 cracks in
the head, with one of them quite large. All of these were clearly
visible without the need for magnaflux. Oh well - time to build
another head. I guess 0.205 off a head is too much, without the set
screws for support. The head was built back in the mid 70's and that
is how it was done then.
In an effort to stay with a thicker head I am considering using pop-up
pistons in this motor. Does anyone have an 87mm set (new or used)
that they are looking to sell?
I know that someone else was looking for a TR4A head, are there any
others available, since it is time for me to make another. Joe(B)
