TR 224 Cam users question

Why is that?? If your valves float. And the pistons touch them. Something is going to bend. Wouldn't it be the weakest part??

Yeah but you don't want the pushrods to bend even before the valves float. It's best to build a matched system; the forces on the pushrods are much lower with the stock cam. You put a high lift cam in with fast ramps and stiff springs, then start reving the engine much higher than you ever did before; this all puts much more force on the pushrods. The valves are going to float at a much higher rpm than before with stiff springs; well over 7000 rpm with Comp 918s.
Another problem with the Weak Link Theory is bending the pushrods doesn't necessarily spare the valves; most people bend those as well. The strategy I like is building the valvetrain to withstand 7200 rpm, then put the limiter at 6750 rpm. If you have a good shifter and know how to drive, you should never shift from 3rd to 2nd anyway.
