e303 timing
So i finaly got around to putting in this e303 i had into my 88 stock heads an valvetrain cobraintake 65mm throttle body - so far it sounds great but i had to bump the timing up a lot to get torque or be able to burnout...is it common to have to advance the timing a lot after upgrading cam?

What's a good spring to upgrade to if, umm... purely hypothetically, of course... one put GT40 heads onto a stock bottom end with a mild cam, and wants to uhh... take the heads back off and have them ported?

The FMS spring kit with proper retainers and locks is $222. I have a set in my garage.
