Make sure the stud girdle is not to far down were the roller rockers can hit the back side of the girdle .

guess that could explain also..
I might have pushed it a bit too far down last time I adjusted..

Also.. Did an "On Head" spring test to test the seat pressure.. 140 all around.. nothing out of the ordinary on #7..

Aluminum heads? Maybe valve seat moved up into the port?

It seems as if a few of the rockers are nicked.. in the general area of where the stud bolts down..

it is posible they were too tight? Nothing looks as bad as #7 intake though.. Maybe I should try different rockers and nuts?

John i just saw this again i see you run a stud girdle so studs should not be moving, as was said make sure the girdle is not to low also have you checked the pushrod length if they are not right it can cause all kinds of problems

I would have thought the pushrods were checked by the builder.. I will order a checker and check them myself..
I was thinking of maybe (while I am in there) switching to a Jesel setup.. what do you think?

looks like they have the wrong nuts for those rockers. The nicks are from rocker hitting the nuts. Different length pushrods wont change it. I'm guessing those nuts came with the girdles,not the rockers. The fat part needs to be further from the top of rocker. Also check that rocker shafts are not upside down, that could also affect it.

tms,
I have often wondered about the nuts being "wrong"..
the shafts might be upside down also.. not sure.. they were installed like that from the builder.. canfield is out of business.. cannot ask them..

Do you think I should change the nuts only? or do the rockers need a change as well??

I have a great deal on a Jesel setup I can grab.. they are 30% off for the canfield heads right now.. as long as they are bolt on I might pull the trigger..
