Ported e6's?

see if you can get one port flow tested to see if they are worth using. Anything over 200cfm I would consider using...........

I'd be hesitant to even waste money on them to get them flow tested, but you never know. I suppose it'd be worth it just out of curiosity.

The other thing is, they would need to have the chambers measured. Chances are if someone wanted any performance out of a set of E6s, they'd want to grind away the part of the chamber that shrouds the intake valve, which would reduce chamber volume quite a bit.

flow testing one port should cost less than $50, for free heads, that's a small investment. If they were done by a "professional", the chambers should have been addressed as well - easy to see and check.
