I wanted to make a real replica and was going to use a MG Midget 1275cc engine, but I got a good deal on an factory rebuilt A12a (1237cc). Im using a 1980 Toyota Corolla station wagon rear end, and like the original Lotus 7 a triumph front uprights(spitfire)

I'm looking for light and if I can get a good 100hp at a vehicle weight of 1000 lbs I'll be very happy. Most people over here are using the Toyota twin cam too, but Championmotor cars here in the states has made a Locost chassie to take Miata parts.
engine, a-arms, rear end..

No problem, I was responding to JSwitzergt he seemed to have oval port heads.

I would consider a trade, but I'm putting my A12a into a Locost 7a replica (Lotus 7) which I believe on your side of the world you call a clubman. The manifold I have won't fit into a 1200 or a B210/210 because it is a little too long. I don't have a space problem while I've been told you guys with Datsun's would.

Both of the heads I have the one on the A12a and the one I picked up on E-Bay (sold as an A14 head) don't have serial numbers. They do have numbers cast into them the A12a has 728 and 406, the A14 has 990 and 409.
Peter Z from Mo, said that the A14 should be able to be machined to match the manifold, I just have to do some work on the oiling from the A12a block. I guess you are saying the same that the A14 round port should be machinable. I'm going to pull the head off of the a12a this weekend so I can comapair the undersides of the heads to see if the one head is different and if the A14 is in fact an A14 one. I'd like to use itsince it seems to be a "New" head.

Where are you located in case I need an Oval port A14?

thanks,
Dog

I picked up an intake manifold for a pair of Delortos for my A12(a). I just noticed that the port side is sized for an oval port head.
My questions are:
1) Can I open up my stock A12a round port head to match the oval manifold ?
2) Can I open up a stock A14 round port head I have to match the oval manifold ?
3) Do I need to find a Oval Port Head
4) If yes to #3, in the US what year and model head do I look for, A14/A15?
4) Do I have any other options, besides getting rid of the manifold.

Thanks for you help.

I just picked up a pair for my Locost 7 for US$75 delivered for both. I'm using triumph spitfire spindles 4 x 3 3/4 inches and wanted to convert it to 4 x 4 1/2 inches. they are aircraft grade aluminum, and 1 inch thick. They are located in Florida, USA and all they do is spacers/wheel adapters. This was the best price I found. E-mail is

I musn't be looking in the right place. I just pulled off the valve cover on my A12a and all I could find were the two sets of numbers 728 & 406. The head ID number isn't on the surface where the gasket for the valve cover goes, is it?

I looker all over again, even with my kMart Specs adn can't find anything. IThe head has valves on, would it be under the springs?
The valves also say In & Ex and it seems to have a chevy bowtie on it? Could some one have put chevy valves on it ? Ithink that the intake was 36mm and the exhaust 29mm

I picked up a rebuilt A head on ebay for
US$ 39. I can't find any ID # on it but it has two sets of # cast into it 990 and 409 on one side. I looked at the Head section here but it only says the A14 had# 990 and 454? It also only has three coolant holes below the intake ports not four?

Any idea?
