Same thing, assuming it is not a early head for 11mm head bolts. I just finnished taking measurements of my new NA cam, I'll be compairing to my stock TD cam when I take my other engine out and see if it really is any bigger.

Supposedly there were some differences in terms of material. The aluminum alloy used for the TD head casting is supposed to be of a slightly different composition to better withstand heat, and the exhaust valves are silicon-filled for better heat transfer as well. Likely not a big deal though unless you are abusing the motor.
The other difference is that the TD head has a coolant flange on the back for connecting to the oil cooler sandwich plate, that the NA D24 head does not have. It wouldn't be hard to pop out the plug back there and drill and tap a hole to make it work, or you could switch to a true oil-to-air heat exchanger using the sandwich plate off a redblock turbo Volvo motor (B230FT). That requires some new lines and some fabricating but it's a good idea for the long term. A D24 head ought to be fine on the D24T if installed well and used without too much abuse... meaning no huge boost pressures, keep the cooling system in good shape, and make sure you get the timing right (too advanced can be hard on the head in terms of pressures and heat). If you are careful about those things, it will likely do great.

Ahh forgot about the coolant flange. Hadn't heard there was a difference in material though.

The NA head has a freeze plug where the coolant flange is on the turbo head. Cool beans, so far so good. Tearing down the NA engine today. I'll be running it as an NA while figuring out the turbo clearance issues.

I see a nice looking late 50s maybe early 60s bug sitting there in the background... What is it with volvo people having air cooled vws too?? Seems like many pictures I've seen over on turbo bricks have air cooled vws in the background too. Kinda interesting..
As for money pit... I know the feeling, but really it was worth it, the new engine runs SO damn good! Jason

The Bug is a 61 Delux Ragtop that belongs to a customer. I'v had more Bugs and Buses than I can remember though. Now Im older and enjoy heat on other parts of my body instead of just my left foot. Oh yeah I like defrosters as well. The 245 will have functioning A/C whenever I get time to finish it up.

I've still got my bug, you've probably seen parts of it in the background in many of my pictures in the garage. Yes heat, a/c, defrost are a big plus... When I was 16 and first driving my bug, I said I would never drive anything but a air cooled VW... Ha! ya right.. I woke up at about 18 and bought a normal car for a daily beater and built a bigger engine for the bug so I could waste the ricers and V8 guys on the weekends...

Ah ha. Thats where the vwjunkie handle came from. Here's my air-cooled sign on my shop.
