Hi All,
Heres my ?0.02 opinion again
I would think there is merit in the solid gaskets on Triumph engines as some types have the head bolts going down through the rocker boxes, so the gaskets have to cope with the higher torque value and the expansion issues
The Velo gasket is a mighty piece and is reminiccent of the auto exhaust manifold gaskets of yore
(reinforced Hallite?????)
Most if not all gaskets supplied for the A 7/10's are made of a very soft material and with the narrow mating faces are almost cut through when tightened
I buy sheet "klingerite" or similar from an engineering supplies place or direct from Walkers
this is more fibrous and a lot tougher, you need sharp punches to make clean holes in it
Anyway, If you go to my "head steady" topic you will see how I cure the dreaded rocker box leaks
Cheers
John O R
