Did the length of the pushrods change from 84 to 86? I just installed an 86 head on my 84 block head and they click really bad so I would guess yes. Anyone have any information on that?
Thanks

I beleive they are the same because I don't think they went to a roller cam untill 87 year.
Did you even bother to check to see if the lengths were the same when you swapped the heads?
couldnt

I didnt have the rods from the other head so that wasnt an option. I just assume that they were different because you dont adjust the lash on those valves.

easy way would be to see if they are the same part number online at gmpartsdirect

They changed to a roller cam in mid 85, or early 85.
