I have just torqued up my new ARP studs - part 254-4110 - on my C3 heads. Then I went to check the fit of the rocker arm mounts, and discovered that those very same studs are in the way!
Have I got the wrong studs, or is it a recognised necessary modification to shorten the studs to allow proper fitment?
Also the heads have built in steel load spreaders at the top of each stud hole. Should the ARP washers be left off? I have used them, and the nuts are also in the way of the inlet rocker mount, so I need to either leave off the washers or use smaller height nuts.
Any advice appreciated.
