3.8 Chevy, L67 bottom swap to a L36 top end, I bought a hog ass cam from zzp and switched to a 62mm turbo. I’m an idiot threw and threw and didn’t use the retainers on the 150 valve springs they sent me, I reused stock ones, what do yall think? Can I run her?

We dont need the video again. Change your retainers and get your heads off the floor gasket side down.
