doesnt valve bounce just mean that the valve springs are too weak to handle the higher revs?
eg I have a 1.5 litre pushrod engine in my datsun and it suffers from it. it (will be) remedied by installing stiffer veedub bug springs in it.
what is the word on hotrodding our 4 stroke engines by installing hotter cams and things such as valvesprings just mentioned?
