Well it's official. Picked up a head today with super tech singles, and a sub conversion. Was not planning on building a head, but could not pass on this deal.
I will probably need some new lash caps, and valve stem seals. But it will be another fun learning experience to put together a head.

Turns out it doesn't have subs so I'll be looking into that.
Looks like the Mazdaspeed buckets are reasonably priced. And then I can get a stack of super tech shims

IMHO, unless you're intending on revving it significantly past the stock redline (which I've heard some people say is not a great idea with the VVT head because it breaks intake cams or something stupid like that), then there are much better things to spend SUB-money on.
Consider that changing the shims and buckets later is a weekend job that doesn't even involve taking the head off. Spend the money on stuff that you can't get to later, better valves or something like that.

Also this is not for choosing to rev higher. I've made my 1.6 see at lest 8.5k maybe 9k rpm. And somehow it didn't die (I think the HLAs are just so gummed up they are solid lifters now)
I would hate to do a 5th-2nd shift and toast everything.
When for ~$270 I could so subs and not worry.

I've 3-2 money shifted before, tach was buried, nothing hurt as far as i know. Personal experience tells me, spending the extra money was worth it.

Lol. This is usually on the track. trying to get down through the gears fast. Last one happened on the front straight at laguna. Pulled it down and the shift kind of felt off, but then when i let the clutch out the tach looped around lol.
The twin disc makes it easy to get into any gear basically. Really easy.

So slow down when downshifting? You're doing it while braking, right? Plenty of time to do it right.
A friend managed to do a 3 -> 2 instead of 4 money shift on my car once. No damage, even with stock shim-over-buckets. Glad for my super light A-beam Carrillos there.
Personally I don't see any reason to do SUBs unless you're intending on raising the redline substantially. NA SuperMiata motors, yes, 7000 RPM turbo motors there's no point.

Parts in last pic can go in a box, no worries.
