@Patriot Racer to the rescue. Need to figure out what locks fit and order some. Not sure how to find that out but I'll make some calls.

@IADR @Mike Beck thanks for talking sense. Clearer head prevailed this morning. Cheap insurance.

@DHR Darren it's dot to dot you whore. Happy belated birthday:View attachment 29286

Now ya know why those grooves were machined in the front of the block, lol.

This is a different model, but they work the same. These things work like butter, I’m not really trying to sell anything, but I’ve tried a lot of different spring compressors and the LSM is the one I like best. I’m not sure which threads you are concerned with, the ones on the heads or the ones on the tool. Neither of them are an issue.

Baller, lol
60° stub thread I assume, like we use on steam/pressure piping valves.

Yeah I meant on the lead thread. Acme thread or whatever.
Just would rather a silent single continuous lever motion over a half second... than acting like I'm sharpening a pencil. ;)
I'll grant I must be wrong on some level, IDK. The one Patriot posts has the obvious advantage of being able to do so on the engine. Obviously going a class or three beyond where I've even aspired to play, that's an advantage, and comparing apples to oranges over a c-lamps style (like the SC2000, or the lever).

Can arp ultra torque be used in place of anti seize

It depends where.
Brodix specifically states the end of the main studs that goes into the aluminum block must use anti-seize.
I don't remember about the blind head studs, but probably.

My logic chain is:

Holes going into coolant get a Permatex sealer.

Bolts/studs that need thread locker get blue or orange

Going into aluminum? Use anti-seize

Stainless bolts/studs? Use anti-seize

Everything else gets 30W oil or ARP ultra if specified

That's what i'm referring to.
I've had good luck with the moroso but my 600lb springs were a bit more difficult and barely enough room to fit the keepers. The moroso will pull or push the spring a bit. Takes a bit of technique. My new springs are in the 800 lb range so I'll be opting for the bench sc 2000.

I like the original arp moly better than the ultra.
No love for peanut butter ? 🤷‍♂️

I've read guys who say the Ultras stretches the bolt to much.

If would be interesting to burnish some rod bolts and then test the stretch using the two versions and the same torque.

They did that on hp tv years ago but..... were they pushing the new ultra 🤷‍♂️
 
Nothing snugged down yet, need to smear a little rtv around the water ports and lock it down.

Need to find my torque specs for all that crap. It's laying around here somewhere
 
I'm seeing most of the internet says torque head bolts to 80-85lb ft for aluminum heads, but my old AFR literature says 100lb/ft on the lower bolts and 110 lb/ft on the upper bolts.

Any thoughts on that?

Gasket mfg will have specs. Follow those.

Torque specs depend on the bolt/stud.
As in ARP supplys the required torque spec and/ or required stretch specs
