Here's the deal

I got about 2K to spend on headwork, I have researched a couple of websites to try to find a "reputable" shop that has experience with a Honda Head. Any suggestions on where to send it.

I was figured a nice port and polish, Crower Turbo Cams, Titanium Springs and retainers...what about rockers? I know I can get a pretty bad ass head for 2K and I want to make sure it gets spent in the right place. Any suggestions on substitutions on the stuff I listed above...I want to portmatch the throttlebody and turbo manifold as well....anybody know the size of the inlet on the Skunk2 Manifold....the throttlebody I am currently running is slightly smaller than my charge pipes so I am gonna do away with that too...is there a 3" throttlebody for honda's?, cause if there is then it will definately warrant using 3" charge pipes as well. Any and all feedback welcomed :feedback:

Oh....is it possible to stuff oversize valves in a B18C head...never heard of it so I assume it is not possible......and......what type of valves should i get....i plan on adding nitrous pretty soon so I want it done right.

I can't help you on where to send it, I deal with old american iron not modern ohc stuff, but I can tell you what works best and is worth the $$.
If you're blowing the motor, you should have the head surface milled flat to provide a better seal with the deck. If you're rebuilding the motor as well, have the deck milled too. Then you can use a copper head gasket which seals and is much harder to blow than a composite gasket.
If you're doin nitrous and a turbo, I wouldn't worry too much about porting the intakes. Especially with nitrous, exhaust is the biggest priority. Get the exhaust flowing as much as possible. Have the intake ports cleaned up, the exhausts thoroughly ported and polished. If you want less compression, have the chambers opened and polished. If you want more compression, have the chambers polished and head surface milled a few thousanths. Get a good 3 angle valve job. Ask the shop if they can install oversize valves.. as I said, I'm a v8 guy, I don't know the specifics. If you really want to go all out, you can get a 4 or 5 angle valve job. I think I've heard of 7 angle, but thats just unneccesary. 4 or 5 is probably unneccesary as well. 3 is the standard good street/strip valve job. As for valves, any 1 piece stainless steel valve is good. Don't use a titanium valve, they'll wear everything else rather fast. Ferrea and Manley are good brands. I've got ferrea 5000 series in mine. If you want, you can have your valve backs swirl polished, it supposedly increases flow a bit. Here are some other things you could consider(this is what I have done to my heads)..
Paint insides of the heads with a smooth, oil safe paint, such as POR 15 engine enamel. This will aid in oil drainback to the pan
Deburr the heads. basically involves grinding any casting flash off the heads. This helps prevent cracks from forming.
Ceramic coat the valves/chamber/port.. Ceramic doesn't absorb or transfer heat very well, so it prevents hot spots in the chamber and keeps the heat in the exhaust and out of the cooling system. More heat in the exhaust means a cooler running engine and a faster spooling/more efficient turbo. I have my exhaust ports, chambers, and exhaust valves ceramic coated.
Teflon dry film coatings.. valve stems and piston skirts can be dry film coated to reduce wear, reduce friction, and to get a better seal. Which brings up another point, valve guides.. trust your machine shop on that, they'll know best if you need new guides.
Gasket match your intake manifold and head... This consists of taking an intake gasket and layin it on the head, tracing out where the gasket is bigger, and then porting the head to match. Then repeat the procedure on the intake manifold. The idea is to get a smooth, gapless transistion.
Hmm.. Head studs are much better than bolts. Always use head studs in a high performance application.
I think thats everything...

Check out the april issue of honda tuneing if you can find it. the article about a a 13 sec integra with 10k includes some info on a very reputable head guy that does just honda stuff. you have to like send him the head and stuff. i tried to find the article on line but i can't and i lost that issue. but that would probally be your best bet. i know some people around here have sent there heads to him.

Portflow or Alaniz are the only people I would have touch my head. Don't waste money on the crower cams, it's like 650 bucks for the pair and you MIGHT gain 10 WHP from them. Yes, you can put oversized valves in B18C heads, but it really is overkill for a street honda. Stay away from anything made by rev.

I've seen dh-racing.com's site a long time ago, and have them in my favorites list. They have a great listing of parts, but I haven't heard or spoken to one of their actual customers. Have you done business with them? I may be interested as well..
