Welcome.

I would buy a second hand engine (around £3-400) and fit a new belt to that before fitting back in to you car, probably the cheapest option.

Spend a few quid and become a forum member, you can then make use of the for sale part if the forum where cars are always being stripped, also you will be able to use the traders section, some big discounts to be had.

Cams produce good gains, will require someone to map the car after though.

Head work I'm not sure on, always been under the impression that the heads are finished pretty well.

If you want to get good advice Chip-mk1 is very knowledgable with these engines.

If you are doing the belts anyway then cams are a good way to get gains, but like -J- said it will require mapping properly afterwards.

There are lots of other things you can do as well, like higher comp pistons and better valves etc, but the gains are small unless its all done as part of a bigger picture, and ultimately you need to be on throttle bodies or turbo or supercharge it if you really want to make a big difference.
