These have been shown on FB brand spanky new 12G940 with all the good stuff already done, about £700.00 apparently, which seems like a bit of a bargain,

Who has manufactured them?

Who has manufactured them?

The post I saw was by Jason Clarke, I don't know if he's the man or not.

Thanks. It says £1600 at the bottom of that post

[GraemeC]

Bare head is £700, built up is more.

[beardylondon]

I’m curious about their set up, and who Jason Clarke is etc, as I imagine this is a serious investment to tool up and cast etc, Anyone know any background?

[Gaz66]

Never heard of the man but there's money to be made in new A series castings I would say, especially blocks seeing as they are becoming rare.
To be honest an all singing and dancing brand new head isn't bad at that money. At least you know it's not cracked 👍

[timmy850]

I know Swiftune has also had new heads made, so they might be coming from the same source? 

[Gaz66]

Some more pics. They look a bit "stripey"
I'm no machinist or engineer but shouldn't they have been faced with a cutter that will do the whole face in one pass?

I think it's fantastic that these are being made available.

 

Top marks to Jason Clarke.

Agreed Spider 👍
Just face em nice and shiny 😁
If your reading this Jason..... Do some 8 ports 👍

Now being advertised by someone else, which seems a little odd. I think if they were more forthcoming in the back story they’d get more credibility.
But top marks for investing the time and money. If they’re what they appear then they should be very good! I know I would rather have started with a fresh casting than have had 2 fail due to internal corrosion.

Now for sale on ebay. Looks like the head gasket face has been properly skimmed. Heads are bare (guides only) £1300. Throats/ports look like they need some tidying up.
