Make sure to take care and not cut bits that you shouldn't! It's practically impossible to put metal back into the head, unless you really want to weld..
Not much else to go wrong really, so just buy a spare 1275 head and go crazy!

Visards book is good for getting the shape idea from, but knowing how far you can take the ports out is done thru experience and trial and error.
I posted a thread on here a while back with loads of pics on a head I was doing for Simon, is it still available Nick?
Nick, how quick would you need this head doing mate? I guess it'll be going on the turbo engine?

That cylinder ports/ chamber are about 70% complete now.
This was done using a pneumatic die grinder with a large carbide bit to do the major grinding, and then a dremel with flexible shaft and a small carbide bit to do all the precision work afterwards...
Removing the beak takes longer than I thought it would (you might really want to do this mod if you plan on using the head for turbo since the beak removed will not only improve airflow in the chamber, but will also lower your compression significantly!)
