Wow.. Somehow I ended up with one of these engines in Montana. So where can I buy an intake / exhaust gasket for a round port A12 head?

Thanks for the info.

A little off topic but what US models / years came with A12 oval port heads? I have one in a AH Sprite and need to be able to go into the parts store and say I want a ??? part for a 19?? Nissan ???. Thanks KW

Thanks for the info Tom. I switched to the DCOE because of a hood clearance problem. I have two 40 DCOE's and thought one would be plenty. I can order whatever but one of the carbs has 30mm chokes and the other 27mm. I bought a header that fit the engine but was not even close for the car. I ended up cutting it up and am starting from scratch with a bunch of bends and my Tig welder. I'll shoot for 2" out of the collector

New to this forum and Datsuns and just started a new project I'm hoping someone can help with. I bought a project AH Sprite with a Nissan A12 and I'm trying to do a little engine work. Engine is stock as far as I know other than a header I am building. I want to add a single 40mm Weber DCOE and need to know where to start with jets and chokes / venturies. I've got two carbs to mix and match some parts but I'm sure I will be ordering others. Can some one get me close on initial jetting and choke sizes. I live in Montana and will be running from 5 - 8000 ft.

Thanks
