my friend just bought a toda head package from this kid--- obviously we can tell that the cams and cam gears are toda--- but we were wondering how can we tell if the spring are really toda, and more important the the brand of spring is making sure that whatever spring it is, it is capable of handling the high 9000-9500 revs---- is there anyway to test the srping to see if they are the proper ones for this application--- just want to make sure before we put it together and rem to 9500 only to find out weve bent a valve and we got rippen off---- any help woul be great

 

Toda springs are slightly ovular, not perfectly round. However, it is hard to notice without serious examination.

 

ok cool thanks----- anything else that i might notice????
