Engine/Transmission (1994 - 1998) Revised ARP headstud kit out for 12V, Heads-up

[Signal73]

I got my stud kit from ARP today, P/N 247-4203.

After perusing the directions I see where the rocker pedestal bolts use to have an issue with valve cover clearance they came up with a design change to support this.

The kit now comes with shorter rocker arm pedestal head studs, and requires machining of the rocker arm pedestal . 200 in deep X 1. 1000 in where the stud goes through the pedestal for valve cover clearance.

Guess I will owe my friend who has a Bridgeport miller a few beers

The kit also includes the secondary rocker arm hold down bolts which weren't previously available.

I haven't seen this before so figure Id throw this out there.

No more grinding the valve covers hopefully Oo.

I sure could have used this setup a year ago when I put my motor together.....

jeez not only did i need to grind the valve covers i had to grind the studs too, i ground the tit off of the bottom of the stud to get them in deeper and that wasn't enough, so i had to skim the top of the stud down flush with the nut too to get the valve cover to sit flat. the stud set i got was a pain to install but i got them for under $200 on ebay so that's not that bad, they were said to be haisley but the nuts had arp markings and they came in a arp box

Grinding the valve covers can be done at home and cheap. Machine work? Finding a reliable machine shop to do said job on your expensive rocker towers?? Hmm... think I'd rather take my chances at grinding a $12 valve cover.

Haisley uses ARP fasteners but the studs themselves are made by A-1 Technologies.

When I installed my studs I milled the rocker pedestal as well as grinding the bottom of the studs down. I don't remember how much I took off the pedestal but I think it was equal to the thickness of the washer, and I still had to mill the valve cover.
