If I am not mistaken, I have read in a TR book, that with wet sleeves, like the
 TR2-4 that they do not recommend moving the pistons with the head not
tightly fastened. I may  have to remove the head from mine and am curious if ot
her wet slevved owners have tried the "rope trick"?

     Ok, am I going to be the first one on the list to elucidate The Rope
     Trick? :-).

     Here goes:

     If you get all of the nuts holding the head off and everything removed
     and you can't get the head to break loose from the block, try The Rope
     Trick.

     Get some soft nylon rope, the small filament kind. About 15' should
     do. Find out which pistons rotate in tandem. On my TR6 it's 1 and 6,
     on the '4 it might be 1 and 3 (just guessing) - let's assume it is 1
     and 3. With all the spark plugs removed, turn the engine by hand and
     watch through the spark plug hole until you see the number 1 piston
     coming up. When it's about 3/4 of the way up start stuffing rope into
     the cylinder. Be gentle but stuff it full. Then also stuff number 3
     full. Then turn the engine over. You can do this by hand or with the
     starter motor. I used the starter and it worked like a charm. The head
     should pop loose. Now just carefully work the head up off the studs,
     being careful not to trap your fingers under it (they're heavy) and
     use things like wooden blocks and stakes to pry and hold it - don't
     use metal tools because of the danger of scratching the head/block
     mating surfaces.

 I am about to replace the cylinder head on my TR4. Found a crack in
 the original one after blowing the gasket a couple of weeks ago.
 What a bummer suffering serious down time in the middle of summer!
 Fortunately I found a couple of places with rebuilt heads on the shelf
 so I hope to be motoring again soon!!

 Anyway, I have just a couple of questions. Does anyone know the
 significance of the numbers stamped on the head. There are 2: one
 on the top, in my case "H220", and one on the side "302137". Just
 curious to know what these mean.

 Also I would welcome any general wisdom about pitfalls to avoid,
 tweaks to be made, or any other insights from those of you who have
 done this before.

Thanks,
