The problem you have is now aerodynamics. You are going to need a lot more grunt with the same ratios to get you machine to go any faster.
It will probably be a common or garden type 9 Ford gearbox. There are a number of companies that can either sell you a rebuilt box with different ratios or the cogs to do it yourself.

Some people are never satisfied
Sounds like you've got a cracking car but like others have said you will need to spend shit loads on engine tuning to gain anything extra there.
Changing the dif will be a cheaper way to shorten the gearing, you could also go for 13" wheels if you don't have them already.
Otherwise changing the gearbox ratios will certainly improve lower down performance but this can be costly.
If it's used for trackdays then learn how to drive with some proper instruction. In performance terms this will be the best investment you can make as the time gains will be huge.

I think i might have a look at a lower diff, im definatly interested in looking at some tuition on the track as i havent been driving for that long, about 3 1/2 years. whats the best way to arrange tuition on the track? can it be done in my car? sorry about all the questions but its all new to me.
Let me get this straight, your car does 0 - 60 in 5 seconds and 135mph flat out and you say it's not fast enough 
Your current limiting factors with a Six are:
- Aerodynamics. Se7ens are like moving bricks so get get any more top speed you need serious power or full bodywork
- Gearing. A company called BGH will do custom type-9 gearboxes with whatever ratios you want. Cost from about £600 upwards.
- Traction. Don't know what size/type of tyres you've got but these make a big difference to getting off the line and going round bends. Fit a set a Yoko tyres on and you'll probably knock nearly a second of 0-60 and have amazing corning ability
- Brakes! Often forgotton but a good set of brakes is worth more than bhp round a track
hope this helps

Get the 14"'s on, it will make a huge difference, the advice on Yoko's is spot on too, try A032r's for excellent road legal grip and like a proper racer you can choose your compound try S(soft) or SS(supersoft). 
Ultimate road legal tyres for 7's are Avon ACB10's with the E mark ie. not the formula ford ones. A bit harsh on the road and totally crap in the wet though
(it's easy to forget to put them on the right way round)
You can get instruction at most organised track days, they have proper instructors who will come out in your car providing it has a spare seat, seatbelt etc. Book this in advance though as they can get busy.

i use graham sykes insurance, they advertise in most kit car mags. they were the only people that would insure me. in was 600 third party and 1100 fully comp.
How many no-claims, what you limiting it to mileage wise? My Marlin (1800TC) is similar priced but no-where near the performance!
