6.1 cam swap. Big deal?

huhuhu, just read your install notes. I didn't add spacers and shims. I simply dropped them in.... bad????

PART ALERT

So my first resolution is to buy some decent valve springs – I’m told the PSI LS1511ML spring is a straight drop in and ideally rated for the cam I am running.

But be aware – you WILL need custom spacers and shims – unless you use the factory “cages”…and they are not ideal…..

Craig from THITEK heads helped me sort out the issue – give him a call!
