I used an ARP one over the winter, worked like butter. Well, it was my first time so I wasn't sure how easily it should slide in, my one piston felt like it caught a little bit compared to the others, so I pulled it out and re-did it, and got it on video:
I'm doing my research in phases. Too much info all at once does me no good.
I am still on the installing bearings/crankshaft and checking clearances so that's where my attention is at the moment.
Once I get that done I'll do more research on gapping rings and installing pistons.
I've never done this before so it's learn as I go.
Okay so JE says min. ring gap for top and bottom oil rings is 0.015" .. my oil rings gap is exactly 0.015". Should I open it up a bit or leave it?

Little problem.
Went to gap the rings and out of the box the top ring is gapped to 0.024" and the 2nd ring has a gap of 0.031"
Little confused here. I ordered the correct ring set for these pistons so not really sure what's up.
Check the part numbers on what you received against what you ordered.

Wow unfuckingbelievable.
The 6th cylinder is just bored out significantly more than the other 5. Jesus fucking christ. My block is ruined and $300 down the drain.

So I brought the block to the machine shop and the owner immediately acknowledged that they messed up and the bore was too big.
He said they will put a thin walled chromoly sleeve in it and should be good as new. My research indicates this is true as long as it's installed correctly.
I'm optimistic they are doing the right thing, I have been bringing all my heads to these guys for years and the always do excellent work and are very quick. So hopefully this works out well.
Excellent update.
sleeving a block is old tech. Should be just fine.

Concerning that they gave you the block knowing it was overpunched. Sh!t happens, but be up front about it. I'd get details on the sleeving and check tolerances before they press it in. Maybe have some more knowledgeable guys on here double check what they plan to do.

Was this the shop you recommended to me? They did great work on my cylinder head.
A member here had a VERY expensive engine put together by "XxxxxxxxXxxxxxxxx", fully built to the hill. Top of the line everything. Arrow rods, CP pistons......the works.
He installed it and all was good for 500-1000 miles of no boost. To break it in. Then once going into boost, he noticed his coolant was blowing out the cap. System was pressurizing.
This was with a cut ring gasket, I couldn't believe the gasket failed, no way. So we installed a pressure gauge in the line from the bottom of the bottle to the engine. The one that runs along the drivers side. Well, he was hitting around 30psi pressure in the cooling system. So, off came the head and what we found was disturbing. The 5 digit engine that he purchased was sleeved on 1 cylinder, and the sleeve dropped. The kicker is, he bought the engine 8 years ago, and it sat all wrapped up in a crate till it was installed.
Shit part is, he bought the engine under the impression it was a good block punched out. They never told him it was sleeved. He didn't provide a block. He bought it all. Then when this was caught years later with only a few hundred miles, that " xxxx " is no longer in business. Many will know who "xxxx" is.
My "solution" would have been a baseball bat to his head, then suck him off while he is knocked out.
That would teach him not to rape.
