I wouldn't be able to say without looking at the engine.  There's a good 
chance the block is warped or the cylinder walls are scored.  Do you know if 
you spun a bearing?  the reason I ask is that the engine I'm replacing had 
spun one main bearing.  To keep from voiding the warranty on my turbo, I am 
required to buy new turbo lines.  I wondered why, until I sprayed carb 
cleaner through one - so much swarf and bearing material came out, it was 

Maybe the shop can get all that metal out of your block and associated 
passages.  Maybe not.  

Speaking of passages, there's the distinct possibility that your internal 
waterways in the block have cracked, which could lead to oil in your water, 
or vice versa.

Not only that, look at the amount of money you'll probably spend:  new or 
even good used parts aren't that cheap - a new head will run you about $500 
alone.  I still think you can get a rebuild or used engine for a better price 
than $2k, but I wouldn't rebuild the one you've got.

If originality is your focus, you can probably find an engine from the same 
year car and swap the engine ID plates.  There are plenty of MG engines out 
there, shop around a little before you dive into a new one.
