i have an extra head i want to send to the machine shop to get decked, ported, and polished, new valves. springs, is getting a head done for an h23 gunna make a big defference cuz i know on a v8 that is were all ur power is just asking for some opinions

 

Well, <U>it definitely wouldn't hurt</U>, just not sure how much it's going to help. The easiest thing you can do to a stock H23 is header/exhaust, as the OEM H23 header is rather constrictive compared to the H22.

That's my opinion...

 

If you have someone who knows what they are doing, you can get a lot of results from headwork, but if the person doesn't know what they're doing you may just waste your $$$. There's different types of headwork for NA vs. FI, springs and retainers will let you rev higher safely, a good valve job will help flow, combustion chamber work can help by improving quench and removing hot spots, blah blah blah, there's tons of variables...

You definately won't be able to get as much power as you would from V8 headwork, but that's what happens when the manufacturer does a good job in the first place.

 

i have full exhaust, aem cold air , i just the head dun and wat not i have a guy that def knows what he is doin i want to get it decked port polished vavles retainer springs so it doing a head would be a waste of money right?

 

In my opinion the tuning and exhaust systems are more important than the P&P for the H23 unless you swap to some more agressive cams that will require you to rev higher. With your stock cams you will be hard-pressed to make power much past 5500 rpm.

I am making 200whp on stock nonvtec intake manifold, throttlebody ports/valvejob. Work on the header/exhaust first, then I would go cams and compression, then while it is all apart I would look into a P&P/valvejob.
