Sorry mate but a 206 is the same as the 295, it's an open chamber design, you can not compare a 202 (closed chamber) with a 295/206 which is an open chamber head

ok ok,,,you got me there,,,but wild things can be done with the shitty old 202, just that i don`t choose to do so anymore in my books, they were only good for practise with the die grinder

Smiffy,
If you are game, you can make a 202 open chamber- here's some pics of last one I did, before chambers were polished. It's a roady head, not race.
Valves in it are 33mm intake and 27mm exhaust (cut-down 1275 ones) in modified Rover unleaded seats.
It went onto a 1220cc Sprite motor in a Minor 1000. Pistons were Hillman Imp- 68mm.

These 202 chambers are now big enough for anybody, IMO- I could have gone further, but the standard 12G295 ones are stupid big.

Very good miniman, not convinced it's a 12G202 mind but then again why would you say it was if it wasn't. Seriously impressed never the less must have taken ages So now you have a 202 thats has chambers as good a standard 295. Now you only need to sort the ports, paying special attention to the short radius and you'll have what is effectively a 295/206. Nice one

Smiffy
This pic above is my head, not TheMiniMan's...
Didn't take long, I used a carbide burr in a bench drill for this... to rough it out.
Here's the work in progress... yes it IS a 202 head.

Very interesting method.

What do you reckon some head work like that would cost, and how long would it take

depends on what ya know and who ya know

The good Dr is working on my 1310 head atm...

willy,
I don't make a habit of this sort of chamber work, as I'm not really set up for it on a commercial basis. But I've done a few... this one was actually to replace a 295 head....
And yes, owner says it went as well or better than the modified (big valve) 295 did.

295s are getting rarer in Oz. I just bunged this up here to show what is possible with a 202. Don't like the 202 closed chamber? Fine... then open it, and then deck the head to suit your C/R!!

you Guys have me a bit worried about getting work Done to the 295 head i Got off Miniman. do u think it might be a good idea to just keep it in storage and Get a 202 Beeefed out for a Turbo Conversion i just dont realy want to Crack the Perfection That i got From Mr Miniman

If you've got a 295 and the C/R suits what you want, I'd use it. But there have been a few 295s crack in competition- I've been told 202s (even when modified) are less likely to do this.
If you are starting from scratch to mod a head though, the 202 is a good starting point. And there are still heaps of these about.
Gafmo has 2 spare 202s at my place, for example..

I have two here.

What sort of money would i be looking at (roughly) over here to get said work done on the head.
The mini1000 racing series is taking off soon and i need head work... quick smart

Would it also be a better option to send it to someone who knows what they are doing (you, Kev, or GR even?)

Get GR to do it

Just send $400+ and tell him to do what he can for what you got

Never seen a 295 crack or seen a cracked one myself. The actually head thats on my girlfriends mini, which I originally bought in 1984 has been on 5 minis of ours, has had 33mm inlets fitted unleaded inserts and a little tidy up by myself and is still going strong. Suppose it's differant over here, if anything ever happens to it i'd just go into my loft and get another one out

I use the method of opening all my chambers on most of my 998 heads i do. the 202 and the 4810, i find it so much easier to work with when deshrouding the valves and also sitting in 33mm inlet valves instead of 30/31mm.

202's can be made to work better than 295 if the right care and methods are used to create them.
The 295 only became popular cos of it being on the 998 cooper years ago and then everyone wanted one, but like the early S design it was flawed in the way of oversixed valves causing cracking, but soo rectified on the sprite and midgets.
Now days we use what we can get cos in 10years time who knows what what will be available.
