toda valvesprings, i have been running these for a while, i got them when they were just about it.

anybody know if they will support a cam with 12.9-13mm of lift without fear of bind? the toda d is 12.9 but the springs came long before. now i went and bought the comp cams with 12.95mm of lift.

and how much clearance is enough if i install em and check it.

tia!

 

send me an outer/inner and the retainer you plan to use and I can measure it for you.

 

As far as I know their springs have never changed. Id give tTom @ Portflow a call and see what he has to say
