68BLKBIRD, Go with a 1.52 ratio full rollar rocker with that came in a 406. You definetly,positively,for surely have to elongate the push rod holes when using a 1.65 rocker with 13's. Start fresh....
This is what I would do...
Pull the plugs,carb,intake and valley pan...
Install...
replace lifters with Rhoads lifters.
replace 1.65 with HS 1.52 full rollar rocker
HiTek comps push rods to "correct length"try a length of 9.100 it should put the tip in the right spot.
Also replace rocker studs with a full 7/16 stud..Big block chevy studs work perfect.
This will fix you problems.
And all big cams make a ticking noise, just make sure your 1/16 of inch down on the Rhoads after adjusting.
To help you thru this get Jim Hands book or do a search for Pontiac rocker adjustment on the net.
Or bring it to some one who knows Phonchos
Good luck!
