i had my heads set up for a b303 cam which has 0.480 lift and i want to do the E 303 which has 0.498. do you think the new valve springs will handle it or should i stick with the b?
i have the e cam with 1.7 rockers (.529 lift) on stock gt40 valve springs. i have been running with this setup for about 2 years now and it pulls strong all the way up to 6k rpms. you should be fine.
