I remember using the Longman alloy 8 port head
As well as the BMC cast iron 8 porter
I was involved with the development of the Cosworth SCA engine (on top of a mini gear box using Jack Knight gear sets)
This was the fore runner to the famous BDA series of engines
We used to fit Janspeed turbo conversions on to B series engines giving good reliable power
Any info on your cylinder heads would be great

Hello John,

What has up until now been quite off topic "what did you do today?" has now come back on topic, as I have decided to get back onto an old project that I had veered away from.

I'm currently working on a new Patentable concept in classic engine after market cylinder heads, so as soon as the tech is properly protected I will gladly share. Actually I'll be advertising the IP to "all and sundry" as it could well be a serious game changer, and frankly I could use the money

As for my billet heads from the old days, I simply copied the important dimensions straight off of the original design, but I pinched a little tech from the Ford Cleveland V8 heads by Canting the valves slightly just about five or eight degrees was enough to dramatically improve the air flow without the head looking very different from the outside, it was just cheeky enough to work. the big "Trick" making billet heads is how to do the water jacket, suffice to say there are some trade secrets that I need to keep just in case I ever go back to that line of work

As for the use of MGA Twin cam heads, on an 1800, it is a pretty straight forward conversion in every respect, except getting pistons, which is near to impossible, I used to make em, as back in the 90s it was out of the question to have a piston manufacturer make one offs at my budget, but nowadays with the proliferation of CNC in the custom auto game, getting the Twin cam heads is probably more difficult than having the pistons made. It was never easy to get twin cam heads, So I made up a set of patterns that were eventually bought by a guy in South Australia who had serious plans, but given that I've never seen them advertised, I suppose that never happened either.

I also designed a range of Limited slip differentials, for MGAs, Bs and various other cars after selling 36 units I got tired of the project and sold my designs and other IP, to my knowledge these are still available today. But as my non compete contract has now expired I suppose I can make them myself again and the new designs would be better as Automotive engineering has come quite a way in fifteen years.

Back to heads, If anyone is interested in building some of these great heads and then the engines, And has the budget, I would do just about anything to get back into it, but it seems no-one has the dream anymore, or more correctly no-one with the cash has the dream. So the new tech has to work on other engines as well, not just A and B series MOWOG stuff. Just to "widen the net" in which to snare customers.

Given my current health, what I really need is an investor with an interest in creating IP and the vision to see that my design skills haven't been affected by being restricted to a wheelchair. With 35 Patents, Seven individual engineering business startups, all of which were profitable, but folks just turn off when they see the chair nowadays, it's pretty hard to take

Best Regards
Rick
