hi all,
just fitted up my new cam and afr 165 heads on my 289 and does anyone know what size the top power steering bolt hole is? the 7/16 threaded rod needs an insert i think it is either 1/2 inch or 5/8 anyone know a fix for this?
any help greatly appreciated as usual :headscratch:

I had the same problem with mine. AFR said to remove the threaded insert on the back of the head, where the air injection hole is and put it in the front. They do sell the proper 5/8"-11 to 7/16"-14 insert but want $15 for it. Found a package of 5 for $15 here locally. Here is the site for the insert, part number 329-7.
