Careful... you have to have a PERFECT head and block deck for the HKS Stopper or it WILL blow! My recommendation would be the Cometic, still needs a VERY smooth surface but it is much more forgiving.
*researching* yea i see they have had some good reviews, thanks Cre. yea after all of this id rather be safe than sorry.

If you're planning on turboing this engine you need to do research into mods which will benefit the forced induction setup. If you are looking to go for an all-motor build (no turbo, no supercharger, etc.) than you need to plan your mods accordingly there too... there aren't a whole lot of internal engine mods which work well in BOTH situations other than forged internals (but you still need to pick because you'll need different pistons for each application), head porting and valve job and (argueably) custom cams.... but in the best situation you buy cams depending on the build.

man i hate being a newb. i guess there is a reason why most people has a tubo'd 7m.

I do not recomment all-motor builds on the 7M-GE.... I know a few people who have spent an absolute fortune on their N/As to not even break 300HP at the wheels. They're not novices either and we're not talking stock-ish build... I'm talking completely custom cams and crankshafts, all forged internals, stupid high compression ratios, port and polish jobs, larger valves... the 7M is a GREAT engine for forced induction... it's miserable as a N/A; A fact which I finally accepted about two years ago.
im totally open to all advice. especially in the key state my engine is in (torn apart) bust since i am going with the rebuild, wont turboing the engine add on another $1G on this build? if not then im not totally opposed to it. honestly id rather turbo this engine now that i know the ins and outs of it. i know that its reliable especially with the metal head gasket, arp botls, new lines and all.

For the replacement head check out local salvage yards where you pull it yourself.... around here they charge $25 to $50 for a complete head... even if you go through 3 duds before buying a good one you're still coming out on top as opposed to what you're likely to pay on Craigslist or Ebay.
none of the reliable shops have any its all good. id rather be safe. sadly all the places here are extremely ghetto.

BTW Cre thanks for pretty much guiding me in this build. ive search like a mother but theres still alot i need to learn.
