i would like to make the springs from the 212cc work on the 420cc because they allow over .400 lift. i ran .360 lift on the 212 and i noticed they only sell valve springs that go to .375 for the 420cc and that just wont work for me.
I guess i could stretch out the 420cc valve springs so the coils are spread further and then insert the 212 springs?
thats what im thinking about doing.
