NO FUCKING WAY lol, the engine was fully re-built and has only covered 3.5k and ive already had the head off JUST put it back on. Ive heard of people modding the heads but i was led to believe that you need a bit of ally welding around the injector cut outs. I agree he has done a good job.....im a little concerned the gasket is going to blow out on boost though, not a lot gets sandwiched?

Im reluctant to take my head off A) because ive already had it off once and had to buy a head set and B) because its had porting/polishing work done, i have an EFI head in the shed.....

That said im pulling the engine back out, so i may stuff tissue down the ports and cut the slots out with a dremel. Worth a thought...
