They have a dish and a deep vr. on the intake side.
actually the piston has 2valve relieves. But its only functional on the intake valve.
still gonna have to check ptv on exhaust side.
If cut one for exhaust, will end up with 3 valve relieves and dish on each piston

I have an LY6, the pistons are dished, and have exhaust valve reliefs, and NO intake reliefs. Here is a pic of my pistons with very small flycuts for the intake valves
I ran a 227/235 @ .050", 114 +4 with lots of PtoV clearence, I would think a 231-239 on a 114 would fit, but as you tighten up the LSA things start to get closer.

the cam was comp 227/.612, 235/.624, 114+4. The cam sounded great, and I guarantee it will run a high 10 in a 3000lb car. needs GOOD valvesprings. Comp has a shelf grind that was the same but ground on a 113LSA
There are better cams out there for sure, and it will depend on if you are running carb intake or not and how much low end you are willing to give up.
I saw you post about this elsewhere, not sure if you are carbed or not...
VVT removal , yes- 4x top cam gear + retaining bolts, ls2 front cover , and your new cam.

I know I already answered all of this for you via PM last week, but since you're asking about it again, I'll post it in here for the benefit of others that may be looking for the same information (ie. what cams MAY fit in an LY6 and how to delete VVT). Maybe this will help someone when they search one day.
My cam is a custom grind that is ground on Comp HUC lobes. It was ground for a single plain intake (carb application). It's a 231/239 110LSA+1. I didn't have to flycut for this cam to fit, but it's in on a 111ICL (one degree retarded from straight up) rather than a 109 as it was intended to be. This two degree discrepancy between where the cam went in and where it was supposed to be was probably just due to a varience in my timing set. But if it would have gone in on a 109ICL I have a feeling it would have been a little too tight on the intake side and may have required a slight flycut to be safe. As it's installed right now, it's got around .090 on the intake and plenty more on the exhaust. This is pleny of room (I like .080 intake and .100 exh), but if I were to advance it two more degrees and put it where it's supposed to be, I think it would be too tight (maybe as tight as .050 on the intake).
If you get a cam like mine, just plan to check your piston to valve clearance. If you don't want to fly cut, just buy an adjustable timing set (if needed) and install it on a 111 ICL like mine and you'll be good to go. Assuming you've got a decently loose converter, I'm sure you'll have no problems running high 10's in a fox body with this combo. My car weighs almost 3500 with me in it and it's gone 11.50s in pretty bad DA. Good luck!

To ditch the VVT you just need to replace the cam phaser/cam sprocket with one from a late LS2 or LS7 (pn 12586481). It will have the 4x reluctor and three bolt holes for a standard 3 bolt cam. Then you'll need an LS2 front cover, which should be pn 12600325. Thats basically all that's required. VVT motors use standard lifter so there's no worry there. VVT motors don't take as much to convert as a DoD motor. I hope this helps.

I guess what I should have said was "now that you're asking about it publically" rather than "since you're asking about it again". My intended point was that I saw this thread as an opportunity to share publically with others what I had already shared with you privately. I never mind answering questions via PMs and I always will, but it benefits more of the "community" when these questions are asked and answered by several people publically.
Between the info that Barrett provided above and what I've now provided about the experiences with my cam and the VVT delete part numbers, someone in the future should be able to search and get a pretty good idea of what works (that is, if you trust the two guys with sig pics of LY6 camaro's lifting the front wheels......LOL).
As always, best of luck and definately let us know how it works out.....no matter what you choose. That's how we all learn and continue to develop our own combinations.

Yes, you need a 6012 for your LY6. I mostly cleaned my motor with brake parts cleaner and wire brushes, but mine wasn't too dirty with less than 3000 miles on it. Things like the water pump and other removable aluminum items (like alternator brackets and such) were ran through the dish washer after they were mostly clean with brake parts cleaner. I use brake parts cleaner to clean a lot of parts because it cuts grease and other grime very, very well and never leaves any type of residue behind. I'm sure others will have more ideas for you though.
