=CDN SS said:I believe one mfg. makes them for everyone and although they say 1.5" they are close to 1.25" I believe that mfg was bot up by Stef's but if you check out their site it should show the mfg. name that I can't remember but think it is B&B ??? I ordered mine direct from him and price was 90.00 fit my GMPP valve covers with Brodix heads fine. ARP makes longer valve cover studs in various lenghts which I highly recommend for no leaks but they sure don't give them away ......you have to call ARP direct to see what length they have in stock
This is correct, Stef's Performance & B&B Performance, same home now.
