Hello gentlemen I have a question my dad’s 1953MGTD has a rust hole that has worked its way through the exhaust runner his head number is what I believe is 88422 next to the Headstud outside of the valve cover and under the valve cover it has a number of 4011F3. I acquired a cylinder head that was advertised as a MGTD cylinder head with a outside (stanmped not cast) head number of AEF118 and an inside head number of 7410F4. Now one thing I noticed immediately was that this head has been milled considerably. The head on my dad’s 53 I milled .070” to bring the compression ratio closer to 8 to 1. But this one seems to be a machine drastically more. First off going by this other cylinder heads numbers what Engine did this originally go on?? I’m starting to wonder if this is a MGTC head. Any input and thoughts would be greatly appreciated. Also what is your thoughts on the combustion chamber sizes. It seems like I’m going to have to CC the combustion chambers before I do any work to this other head. I don’t want to invest a lot of time into it and find out it’s something I can’t use.

I'll have to research the numbers. but two things are certain... one is that is not a TC head. The early XPAG heads including TD's until late into production had banana shaped water ports along with the block..and this one has round holes. The other certainty is the ? head has been dramatically shaved.

The AEF 118 would have been an XPEG head I believe. The proof however would be to measure the locations of the water jackets compared to the 53 head as they were moved slightly to accommidate the new bore size.

AEF118 is an MG TF 1500 cylinder head. Yours has been substantially skimmed, to the point I wouldn't want to use it on a road car. I know a guy with a head spacer he might sell if you want to go that route, but if it were me I'd look for another head.

Looks like someone took a lot of meat off that head! If the head is true and the block the same, with a thick solid copper gasket, it would probably work out. but I would put new studs in the block first, like the ones Tom Lange sells and torque it up. Used as is with a stock head gasket, I wonder how high the compression ratio would go? PJ

If I were going to use that head, I would want to address those spark plug threads. Way too many sharp edges for my comfort.

TF1500 heads are virtually unobtainable. Yes it has been milled a lot but still rare and possibly valuable. George

Can an XPEG head actually be used directly on a XPAG block without modulation to either?
