LB7: To do head studs or not?

[Bustedknuckles]

I just gotta pimp Alligator Performance a little, I called them yesterday at 5pm and ordered my parts, just got home and the head studs are already here!!!!!

Are they pulling the injector cups and replaceing the seals i hope,also theres 2 types of red loctite make sure they use the high temp stuff its good to 450 or 475 and its like a thicker gel not like the super runny regular red

Yea, they are decking the heads, pressure testing them and resealing the cups for $270. I guess that's a fair price? He said he's done quite a few if these heads and said they take special sealant on the cups so I figure he knows what he's doing. Btw, thanks for all the advice and thanks everyone for talking me into studs, I would be kicking myself so hard right now if I wasn't doing them!

[Bustedknuckles]

These aren't in order but you get the idea.

No, its my buddy that was posting earlier, I'm even younger, just turned 20 fwiw.

You have gumption for someone so young. :thumb: It'll serve you well. Hope everything goes as planned on the install.

Thanks man! It's been all good so far except for there is no sign of a leak in the gaskets. Hopefully I don't need a head because I want it running by Saturday evening.

 

[TheBac]

The gaskets sometimes wont have an obvious leak. You really have to look close.
When I took my heads to Eric and brought the gaskets with me, he pointed out some leaks that I couldnt see. The gaskets hadnt officially "blown" yet...just meant the heads were lifting a bit.

 

[Bustedknuckles]

I must have been a good boy, Christmas in September!
Heads will be done tommorrow and its going back together tomorrow night, I think I forsee a late night.....

 

[Sledhead]

This is great, I spent most of a winter doing this job :rofl:

Remember the gaskets are LH and RH :hug:

Great job so far :thumb:

 

[wdino73]

I like shiny new parts...:woott:

 

[Bustedknuckles]

Its going back together tonight, do I need to do a heat cycle and retorque on the studs?

 

[fctry286]

No you do not need to heat cycle and re-torque. just follow the torque sequence tighten to specs and you will be fine.

ARP sends instructions with the studs. Follow those...there is a procedure.

 

[Bustedknuckles]

They don't say anything about a retorque but a guy at alligator performance said I needed to, that's why I asked, I thought not!

 

[Bustedknuckles]

This is not good..... the rear piston on the passenger side is all pitted up.

What do I do now?

 

[Bustedknuckles]

Should i pull the engine and replace it or slap it back together and cross my fingers?

 

[blk smoke lb7]

Its ok i had 1 like that also not a big deal,run it.also i was told by a few people that after you finish torquing the studs to let them sit 3 to 5 hours and go back to do 1 final check in order
