"It'll be nice to actually have a DOCUMENTED Mast small bore thread for once. Then it'll save someone else from all the research I attempted to do.
Figured this info would help:
2004 Corvette M6 39k mile (stock) LS6 short block
Pfadt 1 7/8 x 2.1 x 3 Tri-Y headers
Catless 3"x pipe, thats 2.5" right at the end Corsa Extreme (pretty much a straight pipe; no 180* bends after the over axle part)
Blackwing intake
With the heads I'll be installing the ARP studs (already have)
.40 or .41 head gasket (Cometic or FelPro)
LS6 ported pump
Hinson C7R seamless timing chain / billet gears, Torrington bearing
POSSIBLY Katech rod bolts
Rear will be getting 3.90's with C6z guts and shafts
The kicker here is spec'ing a cam that not only works with the large runner heads, but has sufficient (more than most) overlap to take full advantage of the Tri-Y headers.

If I may...do not hesitate on a very good set of lifters as well as on pushrods.
You will enjoy the investment down the road.

Good to see you stop by, Christian. Hope all is well
Doc,
You might check with ED for the lifters...
For the pushrods, the Manton Series 5-3/8-0.095 should be on the top of your list...
And congrats on this wise buy!
Christian
Badass!!! Now SIG and myself aren't the only ones on the board. So far I've got the heads, morel 4708 drop ins which I got for a good price, ls2 trays, trick flow 8.050 pushrods, and ati super damper, and can't remember what else. Should be sweet when our cars are done. Now you got me wanting to finish mine up again.

You might want to call SDPC. I think it was about a month ago I saw they had LS3 intakes, rails, injectors, and TB's for $500 on ebay. I don't see any listed now but maybe they will have them again soon.

That's not HORRIBLE by any means, but I know I can do better. Plus, the LS3 gold blade TB is useless to me. I'd need an LS2/7 silver blade.
Brian Tooley had some neat cryogenically treated and micro polished stock LS3 rockers with his Trunion upgrade on his website, but it looks like he's out of stock. I'd really like to know more about them.

CRS Cryo-treated and REM Isotropic Finished or Micropolished rocker arms. The rocker arm bodies are individually inspected, cryo-treated, and micropolished. These rockers arms are fitted with our TK001 trunnion kit.

Why not I'd buy them. I don't see new one's a being any better than inspected cryo treated and REM polished used one's.
I'm kind of surprised we don't see more cryo treated parts on here, I've heard valve springs can last almost twice as long, and piston rings and bearing also showing less wear than normal on race motors after tear down. Along with some sort of benefit to treating nearly every other engine part you can think of.

All true statements. I've been thinking about it in the back of my mind on other various parts.
I'm just wondering "how" they were used and why they're for sale, that's all.

No experience with the small bore ls3 heads. However I have seen 3 local cars with the black label ls7 heads. All three ran way better than they should have and made dyno numbers to support the track times.
On the rockers, gm parts has em priced the best but I've read they're pretty slow with getting em out to you. Pace performance has em at a decent price as well. That's whom I bought my small bores from.
Nitrous car ran 9.70's on Radials in a c6z, the two all motor cars ran mid 10's without the driver mod lol. Hp numbers have all been mid 600's with cam and heads, stock intake. All cars were within about 10hp on motor, with slightly different cam specs. The nitrous car was high 800's on a 200 hit.
