What are you using for rocker shaft studs? I cant find an ARP listing. May have to buy individual studs. shorts are 2.5", longs are 3.25".

Big block. I found those on the Hugh's site not long after my post. Thanks for posting it though.

I just order 16 from them 7/16 20 5/16 ball
6 dollars for each ..they have been in business for 45 years. They make rockers arms etc..
Summit is on back order . Its up to you your choice call and see and ask questions.
Make the call on what you need and choose who you want to get them from.
Just another option to look in to.

I just use grade 5 hardware store bolts, tapped deeper to what I need.
I still use the factory hold down bolts, the rockers and spacers are from Hughes Engines, and they are great, I tried Hughes stud kit and didn't like it. I thought the studs were too long and required too many washers under the nuts.
The factory hardware tensile strength exceeds the tensile strength of the aluminum heads they are screwed into so why over kill the hold down hardware.........it will pull out of the head before it breaks.
