just like the title says, im going turbo so i will not be needing these, they are 220cc and 59cc chamber,they are assembled and ready to go with dual .660 springs. 900 picked up and i also have a custom grind cam speced for these heads that i will let go for 200 with purchase of the heads.

 

how well do these flow compared to 243's...

 

Hmm, Interesting.

 

what's the specs ?

 

i honestly dont know man... i do know that these flow 312 at .600 and are one of the best heads for the price!

 

Ttt....
