I'm also a T motor fan. You can get them putting out good power. Try and resist the temptation to go too silly on the cam overlap, and it will remain a very streetable daily.
I ran a 169 Wade cam in mine with a shaved head, mild port/polish, extractors. Motor including bottom end was otherwise stock and untouched. At various times I ran a downdraught weber, or twin Weber DCOEs depending on whether I was working or not. It went like a cut cat and performed faultlessly at every sprint, autocross, motorkhana and daily drive to work.
If you internally clean up the stock headers and run a downdraught weber, no one will even notice you have modified it.
