Sorry I just sold two a couple of weeks ago.

'usually' the unmodified head would be the more 'desirable' for an all out race effort. IF and only IF, whoever is about to do the head porting is literally one of the best out there.

So certainly if you know/do business with a gun head porter, a stock gx head would be the go over one that 'might' have been modified by a muppet and done poorly, to the point that it would be difficult to get it back up to the 'all out' spec you want it to be.

But I think it's a fair call to say that in this case, bige has runs on the board (there's a couple of other names I could think of off the top of my head, some would be known to members here, one or two might not) who are in a similar boat - in other words you'd be hard pressed to find a percent or two of different (tops) between a head done by any of those particular people.

So if the work is done by someone who has got the goods, then it's reasonable enough to price it accordingly - including the cost of the gx head 'starting point' and then the various work/parts they put into it.

If you look at the work Bige has listed for his head, it's actually pretty darn cheap.

Hi, I got a gx head, has been chemically cleaned, pressure tested, has been lighlty skimmed, the valve area has been slightly open for a14 valves, the head has 3 angle valve seat grind for a14 valves! Comes with double valve springs, a12gx valves,a14 valves, needs new valve oil seals, further on everything is inclueded ! Except rocker arms, rocker shaft and tappet cover! Make me a offer I'm from sa, pref sa buyers, if other country buyer must be willing to pay for shipping cost! The head was not used since I got it back from engineers! Contact me on aiden.dom@gmail.com and ill forward all pics

Forgot to add that besides. A14 valves, head is completely std! And has a lot of meat to skim etc

I'd take a head from Bige anyday no questions asked!

Or anyone else off the street

I'm sure bige wouldn't want to go near you Nige....
