Im probably bringing up an old thread, and I'm hoping its been resolved already ,
I bought a set of AFR 165 heads direct from AFR about 6 years ago, and just got around to installing them on a project I've been tinkering with for the last 6 months. (93 302 block stock)
While all the rocker arms a slightly askew , the number 1 passenger side bank is the worse and then # 3 and #4 of the same head are slightly off. #1 is riding with >1/2 the roller tip off the valve stem .
The drivers side head rocker arms are also slightly askew, but all naturally center over the valve tip. I am running the comp cams magnum roller 1.6:1 and Ive tried a set of FRPP 1.6 Rockers, same result,
It looks to be that the stud positioning or the tunnel for the pushrods were slightly off for some of the earlier production runs.. as it seems no one that I have spoke too that purchased them recently has heard of this problem .
I contact AFR, who relented and sent a set of "special" guide plates.. it just looked like they were elongated. and wider. The new plates made the drivers side look great, but no improvement on the # , and made 4 and 3 worse.
I called back since, and they are really pressing back hard on me, One of their guys said they dont see a problem and they would run this with no problem .. BS! Then I hit them with the evidence of , why is one head good, and the other messed up. The couldnt get around that one.. so they asked me to send them more photos.
If it something I am doing wrong , great! someone point it out so I can put this together. But I've been doing this for awhile now, and its certainly not my first build. how can one side look decent and the other all out of wack?
I can't be the first person to complain to them about this, did anyone ever get any traction with AFR. I am 1 step away from taking them to the recyclers and getting scrap money for some Edelbrock or FRPP heads that have worked every time for me.
Here are a couple pics to get you started, NOTE there are two pics of the drivers side , one with my fingers in frame..
You can see the valve tip of the #1 , note the surface wear from the rocker running on one side of it.
