then it can't be from a 2003 (or a Sporting)

got any pictures of it?

edit; is the head the same. or does it differ slightly (or massively) if it is similar but lacks, say, a cam phase sensor (sticks up near the timing belt), and the inlet manifold is made of metal then you have an SPI (aka pre 2000/1) Sei Sporting engine

I don't have any photographs at the minute. Basically I have a 2001 MS and the head went in it and cant be repaired, so I ordered a 2003 Sei Sporting engine and the mechanic tells me that it is a completely different engine, the bolts for the exhaust and inlet manifolds don't line up and the head of this engine is completely different to my origional.
 
If it was just the old head was damaged then you only needed a replacement head from a breaker.

You might have needed to grind the crank case interface flat and/or salve any erosion. But if the bottom end was good I'd a wanted to retain it - as engines from breakers can be past their best before date. If their auto was rolled, at speed it wont have done the engine any good

A head from a breaker might have needed a grind to flatten it, and the valves ground and tappets adjusted, but that is a simple job.

It would have taken me a couple of hours to replace a head a weekend to replace an engine. I'm rather slow and methodical.

The replacement engine needs to have the same part number prefix unless you are into radical tuning like fitting a larger engine for torque, larger throttle body etc...

Hi guys

Thanks for all the help and advice, turns out I got an SPI engine by mistake but I managed to get an MPI one which arrived today so should have the car up and running again soon.

Being a Schumacher, I would have thought that you'd want to keep the matching numbers.

I did originally want to keep the matching numbers but I found it hard to get a head on its own that was in good condition, so I chose just to get another engine. I am going to keep the cars original base and I will look for a head which I will put on eventually and put back into the car.

Thanks again

Aaron

PS. If anyone needs an SPI engine make me an offer, I have 1 going spare lol
 
so you are needing a SPI head??

I needed a head for an MPI to go on the cars original engine but I found that most scrappies only wanted to sell the engine as a whole unit so decided the best thing to do is buy the whole engine, but I accidentally got an SPI engine last week which is no use to me. But today my MPI engine arrived so i am going to put it into the car and take the origional engine out and put the new one in to get the car back on the road.

Your current engine is a known quantity.

If it was me, i'd remove the mpi head of the breakers engine. Get it skimmed, pressure tested, and the vlaves and seats redone. Tha'll only cost £30-£40 and then you know the head is a+.

Then it's only a few hours work to swap the head over :)

The breakers engine may have all kinds of problems, and you'll be cursing if you swap it all over and its a heap of junk ;)

If you were goning for a full engine swap, it would have been a perfect time to fit a punto 75 engine instead. Pretty easy job, and 21 horsies more to play with :D
