DOHC Head on a SOHC Block :D

As the title states. 

After seeing the different things people have done over seas in OZ and even here in North America I cant help but be obsessed with doing this for myself.

Though I am going to start with an A12 block and adapt a DOHC head. I have full on plans to do the same for the L16, L18 and L20. Some might say "whats the use considering we have great DOHC engines already".. I was in that company and mind set. 
To that I say now " I have changed my mind.".. Since having the CNC at my disposal along with the engineering software the initial investment is covered. Its all parts n time now. This will be an enormous exploration for me. I have the basic knowledge of how our engines work but no way am I an engine professional. Which leads to the needed assistance of most of you that have this expertise that I lack. 

I can design, align, and create the items, but lack the exact knowledge to make this run. I will do the best to mix this project in with the coming Datsun billet goodies I have on the horizon, and my 1200 car sitting in my driveway 


So here is my starting point -OIC's will be on hold for now-

Block: A12

Potential Heads:

K1200RS BMW
Mazda Z5 16V 
KIA Rio 1.5 16V

I picked these heads for the external cam pullies and how they are cog belt drive. The Mazda heads have been adapted to the Datsun-A block before so that would be a good way to start. 

This will be an available item once things are completed and the wrinkles ironed out. All opinions are welcome should it be toward the success of my goals only, but should you be contrary I will call you a racist.  (not really)

All opinions welcome.


Thanks for reading.

I am gathering all items involved but would like to source the crowd for a Mazda Protege 1.5 ltr DOHC head. This is the one I have decided to try. 

 

Would anyone in the Oregon, Lower WA, or Upper CA area have any  feelers out that could land a budget 1.5 ltr Protege Head that isn't destroyed for reasonable $$ or even donated to the development of a 1200-A12 Block to DOHC DIY Kit?

Matt, the things you get to do are just too much fun

[ggzilla]

Except the,A12 is not an SOHC engine ...

A12 Donor and 1.5 head gasket in hand today. Gotta wreck yard shop for a head tomorrow.

Found a 1.5 ltr Miata head for 100$!! I think I will thank you.

 

Edit: The head was a junker. Bearing journals were toasted. Looked like it had been grinding for a while.
