Hi, i'm going to purchase an alloy head for a turbo 1330 with a garret GT13, is it worth getting bigger valves and mild port work or will the standard head do?

I'd say "yes", maybe look at what they say on turbominis forum?

Also, alloy 5 port or 7 port? I'm not sure I see the point in an alloy 5 port..

I'll most likely go a 5 port to keep things simple and stay within budget, finding a good original one costs about the same. Is there much gain to be had with a 7 port?

oodles!!

a decent amount of space behind the engine for your turbo, simpler plumbing for your intercooler, plus you can fuel it properly - port injection
