I am cleaning up my head while off for a new gasket.Early high port according to Terriannes site,5/116 int.,3/8 ex. and 2 springs on intake three on exhaust.
Head was done before.2 ex seats have been replaced,the rest ground.All have varying shims.4 ex valves will be replaced.
What is the installed spring height for the int.and ex.valve springs?
Or what is the installed pressure,so I can shim accordingly.
Thanks
Tom
