OK RR, but as of my earlier observations, the intake may still have some kind of sealing issue, just not a massive one...
That being said, I probably will go back to square one and very probably most likely swap intakes as I just am not confident in this old Torker, and a good dual plane may help, and also I will eliminate the end seals entirely just on GP.
With the light springs in the distrib. I may well be into the curve already.That won't help either.
Thanks
