[TR] any TR7 folks put on a clyinder head using ARP bolt kit?

[Randall]

My approach would be to find out what ARP recommends for the TR7, and copy
that.  While I haven't bought any, I've seen that kit, and it appears to me
that ARP did some engineering (in the form of adding reduced diameter
sections to improve elasticity) to better track the changes in head
thickness (vs stud/bolt length) over temperature.

Although TR7 heads aren't identical, they are close enough that the clamping
problem should be exactly the same.
