The Original Cylinder Head Shop, Louth, Lincolnshire
36 Years Of Top Experience In Cylinder Heads
In1988 with the advent of the introduction of unleaded petrol, we made the decision to concentrate on cylinder head Engerineering rather than building motorcycle engines. Being used to working on high power to weight air cooled engines, We had to work to a level which exceeded the average water-cooled unit used in production engines. We invested heavily in the World Leading French, Serdi Specialist Machinery at great Expense. This equipment was being used by the worlds top racing teams and the price reflected this fact.

Thanks Len.
You may possibly remember working on my very rare bronze Ariel 500 cylinder head, it was about 7 yrs ago. It was good work and the engine runs very well – although it is now a 680cc not a 500 single. As the project took 10yrs with lots of help and work done by others, I have written a book about it, well illustrated, and with you and others acknowledged, contact details as appropriate.
Best of luck at your new location and in the coming new year.
Cheers
I’m just checking … back in 200? you prepared a Daimler DB 18 cylinder head for me. Your results were exceptional. Please could you tell me if you are still operating from the same location. I was one of your early customers just following your move from London.
Best wishes. Hope all is well for you.

Hi Len, I took delivery of the engine parts today.
The parts look great – better than new ones! The valve seats & guides look & feel brilliant.
I just want to tell you how pleased I am with the work you did on a pair of heads for my Moto Guzzi LM 3 – after so many bad experiences I finally found the right man!
I also want to congratulate on your starting up on the new premises in Hastings. I would be happy to pack a pair of Guzzi heads and visit you in Hastings and stay a couple of days to explore the town and check out the music scene and see what draft beers are available.”
Since, I had my cylinder head refined by “The Cylinder Head Shop” I gained an immediate 10-12 “horsepower” increase alone with an increase of torque as well.
The cylinder head which I am referring to is a 2000 Yamaha R1 cylinder head which now produces 152 horsepower at the rear wheel on pump gas and 78 foot pounds of “torque” just from the cylinder head being reworked and refined by the Cylinder Head Shop.
I tell [you] what, these folks know exactly what it takes to refine and rework a cylinder head so that there is an increase in flow, horsepower, and torque … believe me I’m living proof.
I recommend you to people who have trouble with the head or heads of their bikes. You did an excellent job on the four-valve head of my Enfield. It has done very well for almost a decade and still does well, the valve stems stay well, no wear apparent, before I take for a ride I oil them, it’s all in the open air. It was my plan to cast new heads using an original head as a pattern./strong>
All the best
Hello Len, just a line to let you know that the T100T head that you did for me is nothing short of perfection. The bike runs superb in every way in fact it is like owning a new machine. The confidence in its reliability and the fact of not having to search for LRP or other additives is a joy.
I wish you many years of successful business and good health to you and your family as you are in my increasingly short list of people with skill and pride in their work in this 21st century. Cheers! Len many,many thanks for the pleasure you have given me Fred (from Hull).
Len, My apologies for the late acknowledgement of receiving Triumph head. Your usual faultless work. You guys are the BEST and you can quote me.
Dear Len,
I completed the assembling of the head which you repaired. Please look at my Triumph! Your head repair was perfect! I show respect for your machine engineering. Thank you very much for your kindness.
Hi Len, I have now put the head back on the Triton and had it tested. I have some troubles with the magneto, not giving sufficient sparks, but we had a reading of 44 hp on the wheel and pulling almost 40 hp from 3000 rpm and I think there is more to come with a good magneto. I am very happy with the result! I’m racing saturday and very exited.
The bike is now running very well in the power department. I had it dynod to sort out the carburation which was all wrong. The bike produces 86bhp at 8000rpm and 62ftlbs of torque between 5000rpm and 8000rpm which is acceptable using Jota cams and standard 9 to 1 compression. The carbs have now been set up which has sorted out the top end (much too rich) The atomisers and needles need changing because they may be worn and are too rich. All in all the fuel consumption is 34 mpg which is for all round fast riding. I believe this will increase when I have sorted the rest of the fuelling. The bike does seem more powerful.
