Sorry kinda long again...
Boy did I start a mess. Wanted everyone to know that I called Jason at AFR and worked out the problem. Everyone should call him and not the other guy (not going to say names). Jason explained that AFR will take back the heads that I have just because the the head stud holes are two different sizes. I opted to keep them and use the ARP reducer spacers that I bought.
The two different part numbers that are on the heads were expalined in a prior post from Jason.
I wasn't aware of the header bolt problem. I thought that the 1" ARP header bolt would work on the AFR heads. I had problems with the 3/4 in header bolts that came with my
BBK headers. The flange is 3/16 thick and the bolts were always loose after a road trip. Always had to tighten, just would not stay in. I found that they were only going in a few turns. So I bought the 1" ARP bolts from Summit. Now, I will be taking them out and grinding them down a bit so I don't have to use the washers.
I still am unsatisfied with the rocker studs that come with AFR heads. The length is not right at all. The rocker nut only tightens about 3 turns until it won't tighten anymore. Its just not long enough! Jason gave me the part number for the ARP studs, that I will get soon. I still don't understand why AFR doesn't include a quality ARP fastenter with their quality head. Who knows keep price down? The chevy guys get the ARP rocker studs with their purchase of the AFR heads, Jason's co-worker at AFR told me that.
The summery for this post is call Jason at AFR he will take care of you... If you get another person hang up and call back later or take your chances. I bought my heads from a good retailer that gave me free shipping and are super good to work with. D&D Motorspots out of CA. I re-read the article in MM&FF last night about the camparison on the 185 heads I am excited to get this project done and get back on the road. Getting a dyno tune next month maybe I will be back with a new post.
