Where are you located ?

Stripped the head today, and it turns out that the reason there is no exhaust valve wear, is because it is already fitted with non magnetic valve seats and valves ! No idea how long they have been fitted, but the seats are really good !

Makes a change to have something go my way !

I suspect the only things you could do are to either just replace the one you have if it looks at all damaged or worn, or invest in some "V" blocks and measure lift and duration and compare with the standard MGB cam.
Piper cams are well worth fitting in my experience.

I don't really want ...

I know the likes of Kent and Piper are marked, but I was hoping for some info on factory fit items, but it seems no info is available.

Is there any sort of resource where I can identify OE Factory camshafts ?

A series engines were marked I recall, but B series items appear to me unmarked.

Thanks Ian
I am down in Kent so Mr. Burgess is quite a way away.

I am primarily concerned with the quality of camshafts and followers, as these seem to be problematic. Rover V8s are a prime example, almost impossible to get anything worth having at a sensible price.

As there appears to be no easy ...

I am in need of some engine parts. Looking round, there is a lot of variance in prices.

But as most stuff available is non genuine, I suspect most of it comes from the same places, and by my experience with other vehicles, a lot of it is carp, and made of the finest Chinesium.

Is there a favoured ...

The reason for doing this swap is mainly because the original engine is shot. Lowish compression on three cylinders, which did not improve with a wet test. It must have stood idle for a long time, as most "classic" cars do, one the novelty has worn off. There is rust staining on the cylinder walls ...

Those "magic balls on a string" are absolutely no good at all. They're about as useful as a chocolate fireguard and a big con trick. Get the head done properly that's the only solution.


Whaaaaaaaat ? Surely not :lol: I have the brochure that came with the car, and they are guaranteed to work ...

It's worth bearing in mind that the parts that could potentially be eroded (valve seats( are the self same parts that are replaced in the unleaded conversion process.

I intend to wait if/ until any wear arises and then replace the valve seats. Given low mileages plus occasional shots of a lead ...
