No. Look at the size listings on the rockers shaft orifice.

The stock stud has a 7/16ths bottom and a 3/8 size upper shaft.

The ARP studs come in stock, but you should really get a 7/16ths stud that is the same on upper portion and lower. This prevents flexing, making your valvetrain/rockers more accurate.

I say buy 7/16 SBC ARP studs, and get 7/16 NSA rockers, guideplates, hardened pushrods. This is a way to ensure you wont be selling anything in the future and be content with your selection.

Either way I would go 7/16 no matter which stye rocker (nsa or SA)

that stuff is not needed, how much spring pressure are you planning on running or how many RPMs you turning.

I will say some people are more plug and play and others do not want to do as much. The 7/16" set up takes more time than the SA 1.6 RRs, ie you have to make sure the GPs do not scrub the PRs.

And do they make SA in 7/16"?

Good point Shon, it just depends on his future with the vehicle on his decision. If he is like me I like to buy once, but my goals are different im sure.

They might not make a S/A 7/16ths now that you mention it.

Yeah I am more a buy it once guy. But the car is more a daily driver then a track car. I know it has 4.10s but im going to do more cruising and light to light than an actual strip or track car. Itll probably see at most about 62-6400rpm.

The cam is going to stay stock for now also, and when i do the rockers I was going to run LT4 springs wth trickflow pushrods.

Agree. That way in the future if you want to upgrade your cam you won't have to sell the parts.

I shift mine right at 6200 and it pulls hard all the way there.

Found these on ebay.

Gonna try them myself.

Uncool, I would go for an aluminum rocker over steel.
