Re: Holroyd BBC Rocker Arms
The rockers Clark uses are Marine, identified by a particular marking inside the rocker. He has machined a re-inforcement that fits above the pushrod seat and is welded into place. The design is a nice fit, with an oiling hole that aligns with the hole in the rocker. I doubt you could do these yourself for the money, unless you could design them and had a cnc machine capable of making the inserts and did not count your time. I just got mine back from being upgraded, Clark is great to do business with and IMO his stuff is top notch. The Stud and adjusters he makes to use with these rockers are beautiful, sure they cost $$ but for a limited specialty product worth it....they are also legal as purchased from Clark.....
my 2 cents...
