Ive been searching for the answer, but come up empty handed. I bought a used set of CTR cams with valvetrain. The all 16 springs are dual, 8 have green paint and 8 have blue paint. ITR calls for blue on exhaust and yellow for intake, cant find info on the CTR, just wanted to confirm that green is CTR intake.

Thanks

 

Bump for day crew.

 

blue should be exhaust, but i had yellow not green for my other color not green. hope this helps a little

 

itr & ctr valvetrain are the same

 

Would anyone know what dual green valvesprings would have come out of then?

Thanks for the help guys

 

For those wanting to know, Green dual valve springs are B16a exhaust springs.
