someone told you bullshit....having said that it depends on the lift as to wether the stock valve spring will coil bind.
Cams like the BC272 can be used on a stock spring....I have a set of these brand new if you want to get a measurement.

Depends on the cam lift as Brian said.
As a rule of thumb for our 4G63 engines, I would strongly advise that if your cam lift is going to be above 10.2mm+, then you will need to replace the oem valve springs with some aftermarket h/duty valve springs to handle the higher lift without risk of binding.

just thought I'd put it out there but ramp rates will play a part in the valve spring issue too, eg kelford 272's are very aggressive and will more than likely cause float, but im not an expert just thought I'd mention it
