right it is not knocking part throttle , just the upper rpm range , 3800 up maybe a bit higher /
Not sure we have E-85 up here , at least never seen it at any station . . Hope it does not rain friday so i can get to the shop and tet out some of your ideas . Thanks , will let you know how it goes . .
Worse comes to worse AI'll change the heads , something Aluminium sounds good .

Well the other option if playing with the distributor doesn't work would be to recam it. But honestly, I think changing the cam timing would be the better way comparing those two. But again, all this heavy work is puttin the cart before the horse, as you may get it nailed down through working with the distributor. Good luck with it.
