I've got my engine halfway torn apart, and I'm swapping in a hotcam.

I bought ARP 3/8 rocker studs. What is the best way to pull the stock studs out?

mdacton

you unscrew them, lefty loose

Malice 1

Yeah, but how? Do you put a double nut on them or something?

Stl94LT1

No, just get a deep-well socket and unscrew them.

Malice 1

The ARP studs that I'll be installing have a hex at the bottom, so I can screw them in with a deepwell socket.

The stockers don't have that. They screw directly into the head with no base hex.

Stl94LT1

Are you sure? These are stock 1994 LT1 heads?

Malice 1

THey are stock iron LT1 impala heads, according to the casting #. I guess I should have said that earlier.

Stl94LT1

Oh, those may not be screw-in studs. If not, I have seen stud pullers you can buy. But, you would have to have the heads machined for screw-in studs.

why do you have iron impala heads on your camaro?

The_Bishop

Those aren't screw-in studs, they're press-fit. Only way you're changing those is by pulling the heads and machining them.

Stl94LT1

Sounds like it may be time for a set of aluminum heads.

sbs

why are you replacing 3/8 studs with 3/8 studs?

TheChronic

Ya, those are press fit.

it had them on when I bought the car. Plus, I'm told they flow better than alum heads.

because I didn't want to buy new rockers, and I'm not installing a big enough cam for 7/16 studs.

that blows. I guess I'll send back the studs.
