shave the head as much as you can, increase's compression heaps and makes a very big difference to performance and economy. you can also put holes in the head just above every exhaust port at the manifold mount plate, screw in a nipple in each and plumb it back to your top radiator hose.
other than that, port match it and bolt it all back up.

I have seen the same done on TD42's also. Main reason gets rid of hot spots in the head.
