Cylinder head question

I am considering buying a ready build uprated h22 head, and then putting in some big n/a possibly skunk2 stage 3 pro cams. I don't really want to touch the bottom end of the lude yet as its already got 11.1 pistons (a8) but possible future plans may change that.
if I buy this head and put in these chunky ass cams (already have an atr inlet ready), then have it mapped in via the Hondata, do you think I shall gain much? I mean more than I already could with the a8 cams which are the equivalent to the atr or type s cams? or is there no point until I can get the bottom end forged with bigger pistons etc.?
thank you!

Shunk2 Stage 2 Pro's will be the right ones for 11:1 comp pistons. You don't need stage 3's until you are running higher comp. I have the stage 2's and I have 11.5 comp Mahle pistons.
What has been done to the head?

full ported and polished head
bronze intake and exhaust valve guides
racing valve stem seals
Brian crower big race steel valves
brian crower titanium retainers
Brian crower stage 3 Custom turbo camshafts
skunk2 pro series cam gears
brian crower dual valve springs rated at 10000
all chambers balanced
multi angle vale seat job
Just copied that from the advert.
Been looking at forging it but it's a big cost

Never will I boost a Honda lol. It did have turbo cams in it but the guy will take them out, then I can put NA cams back in.

personally i think stage 3 will be over the top for your build, i have stage 3 but will be running 11.5-1 pistons and have taken a fair bit off the head and a little off the block aswell as having flat faced valves to further bump up the compression. I also have a set of ITB's to bolt onto her after aswell as as 3 inch exhaust and fairly heavily modified exhaust manifold. i was still in 2 minds wheather stage 3 would be too much

I have a 3 inch system, manifold isn't as big tho, would the gains be worth it with that head and stage 2 cams? Would like to forge the engine but it would have to wait till my other car is finished.

Yeah, there'd be no point considering SK2 Stage 3 Pro cams without serious bottom end work.
Also, do you know what standard of P&P work has been carried out? Is it a full race spec or just a light P&P?

I believe from the spec that its the Crower filled head from that Accord Type R Turbo build the guy is breaking. He has/had the bottom end for sale on ebay too.
