I dont really want to remove the heads just for this.

 

Well unles you got an efficient way to keep all the metal shavings from going into the lifter valley.. then yeah it's possible. I wouldnt take the risk though... lol

You pretty much have to remove the heads to install screw in studs due to all the metal shavings you get from the machine work and tapping of the holes. Personally, I wouldn't risk trying it with the heads still on the engine. Hehe, looks like Blade beat me to the punchline by like two minutes.

if all you had to do was pull the old studs and tap for the new ones i'd say yeah go for it, tape all the opening off and use some magnets to catch the chips. it's a little more involved than that so unless you have differant set up on your studs than the ones i've used (arp) you have to pull the heads.

That's also assuming you'll be using the poor man's screw-in replacement stud. It's designed to replace a stripped stock stud by simply tapping the hole and screwing it in.

If you want proper screw-in studs (ie: ARP) that have a hex base, you need to have the stock stud boss machined off so the new studs have a seat to sit against.
