I know this may seem like a silly question, but what are you hoping to gain by all of this?

you're likely looking in the wrong area. usually these dohc flow much more than adequately, they really need cam and compression, and EXHAUST and TUNING.

If you want to fabricate something to help it fabricate a header and exhaust, then figure out how to tune it- a much better place to spend your time and effort.

I applaud you for all your trying to do.
One of the neat things about the newer cars is all of the EFI and retuning via a lap top or re-programer.
If your looking for just a few more HP, how about just getting a re-programmer?
I did a quick Google search and came up with this:
Venom Performance Control Module Venom 400 Engine Management Piggyback | HorsepowerFreaks

Theirs not a bunch of room on a 4 valve head, the only place to unshroud valves is at the top of the cylinder wall, depending on how far down the piston is in the bore. After working on that Mazda head I couldn't really fine any room to do anything except clean it up some. A reprogramed ecu like Mr.Williams said is the easiest thing to do if one is made for your car. An ecu. can be fooled a bit by using cam shafts that open/close valves sooner or later an not changing the lift any. I think most everyone who has posted is thinking V8 heads not small 1.8 or 2.0 L head.

2.0/2.4l head I believe, and yea, most people don't realize these things are a different animal. with stock cams the only improvement you'll see is from blending in the top and bottom cuts of the valvejob, and even that won't be huge.

If you're serious about working on this engine then you need to look at what really needs attention, if you're just bored and have a grinder and some cartridge rolls then go ahead and smooth it up, just don't remove much material and you won't hurt anything, won't help much either but it's a way to kill time.

your exhaust is a major restriction, your tuning will need some work, and if you can spring for it there are cams out there.

Bought David's book before I started taking the engine apart. Great book. Even after reading it twice, I wish I understood it all. I now have the heads off and need to read it a couple more times, and develop a flow bench like he suggests. A lot of reading, and work, but, saves a lot of money.
