need 3500 rocker arm studs

Actually, while were on the subject of oil. Does anyone have a good oil viscosity/ brand to recomend for an engine enduring this kind of torture.

that high of rpm, what are you going to be doing about the bottom end bearings?

I'm removing and blocking the #5&6 oil squirters and widening the main-oil channels feeding the crank to boost oil flow to the mains. Ill also be using ARP main-studs with two possibly three "double-stacked"/ welded windage trays. (It'll also help take up the extra distance left behind by the longer threaded studs)

Id rather use a main girdle, but I dont have the cash to have one machined out. Hopefully I wont find glitter in my oil-filter after my first hard run.

Which rockers exactly? I would like to see what they have that is compatible. ARP makes 8mm studs but I don't know if they would work well with what you have. You would need the adjustable nuts for on top as well.

Drilling the heads for 10mm would be a real PITA to get perfectly straight.

You mean those??

What rockers are you trying to use??

Im using a set of Crower cromoly steel 1.6:1 roller rockers. Its neccessary to use adjustable rockers since Im using Crane solid roller lifters. Solid rollers are a pain to keep adjusted, but they're vital for my set-up. This motor will redline at 7500rpm and needs the additional valvetrain stability. Hydraulic rollers begin to float after 6500 rpms.
