If you are using shim under bucket lifters, it is a pretty easy operation to grind down the shims to get just the right fit using nothing more than sand paper, a flat surface, and a dial caliper. It might be possible with the larger shim over, but I have not tried it.

Alright so I feel like I haven't changed my setup enough times yet, so here we go
New (temporary) setup that's ordered and in the mail:
Garrett GT2871R turbo
BEGi log manifold and S downpipe
FM silicone intercooler piping
Vibrant 350HP intercooler
Turbosmart bpv
I decided I wanted something basic and simple to run for now until EFR kits are finally available to us, so once this stuff comes in its getting installed right away, and as soon as my valve seals and shims are replaced I'm driving the car as much as possible. Tired of constantly wrenching on the car and not enjoying every day boost.
I'm really pushing to be completely done and driving/enjoying before Christmas.

Not sure how much could be felt in pedal feel, but it always felt nice.

Not on my own cars, but others' and really liked it.
Thanks man
Once you get the new valve seals and such on, the entire community will thank you if you do a sticky-worthy write-up on the "rods only" rebuild. Speaking of that, supposedly the stock pistons can take 300 whp. The 2871 is right at that in its efficiency range, right?
And that 300 figure is on pump. I don't think anyone has ever found out the stock pistons limit on e85. The 56 trim 2871 .86 should be good for high 300's
*edit: to be clear, I don't intend to reach high 300's, but here's the compressor chart anyways:
Its quite a bit more potent than a Disco Potato 2860

I think you're misunderstanding me (and likely I'm mis-stating what I'm trying to say).
1) we don't really know what the limit is. 99.99 fell apart from detonation or heat or something else. savington threw out the 300 figure because he's seen 1 or 2 fail past 300 without any obvious signs of detonation, so we just kinda "went with it"
2) e85 reduces detonation to nearly non-existence, and is cooler. Neither of those properties make the pistons "stronger", but I'd bet it would handle more power due to this. My previous NB is still chugging after many years of boosted abuse, and put down 307 in my possession and I was sandbagging it so bad its not even funny. Basically the turbo wasn't even in its efficiency range. 14-16psi LOL
Again, I'm not claiming or stating as fact anything. This is all kinda "what we've seen/learned" type of scenario.
*edit: anyway, the ST valve seals came in from Emilio. Time to start wrenching on this thing

SST? Drawing a blank here.
No I really don't want to pull the head if I can help it. I'm going to try to either pressurize it or do the rope trick to keep the valves from dropping.
I actually had an idea that could either be genius or retarded:
Get a strong/tough inflatable baloon to pressurize the chamber, so I don't kill my compressor trying to keep up with the escaping air for the 20 minutes I"ll need per shim. Think something along the lines of tire tube.
I haven't seen it done here, but having a hard time seeing any flaws in this logic?

The balloon thing might actually work. It makes sense, you are just trying to keep the valves from falling into the cylinders, right?
Whatever you do, get pics. I want to see how/if you manage to do this without removing the head.
