Roller Rockers Geometry

I know it sounds strange but mine only made noise on accelleration too. After I installed shorter pushrods the noise went away. I just read your post below where yours are clearing the pushrods. Do they have excessive side clearance that is allowing them to slap back and forth against the hold downs? Mine seemed to have alot of side clearance I noticed.

If you don't find an obvious problem at the rockers to make sure it isn't spark knocking maybe you should check the timing to make sure something didn't slip there. Maybe try backing it off 3~4 degrees degrees just to see what happens. That'll rule out if it is actually spark knocking or not.

No I don't have excessive side clearance ... everything is very healthy in that area. I have checked everything.

I just cranked the motor up, waited for it to get warm and checked the timing. It was off. I usually run it with 34* all in past 2500rpm. It was in the 40* area. I backed it off back to 34* ... I would test drive it but the roads are wet. The cam has the lick it used to have now. I wouldn't think changing rockers would have a effect on timing but I guess it does. I didn't touch the distributor the whole time while installing the rockers.
