Help!!!
After pulling the passenger valve cover I'll know for sure but thinking I have a failed spring in my AFR Mongoose head. Tell me if I'm on to something here. Truck starts and runs fine @ idle and under 3500. But on acceleration, the motor loses power and shudders as if the exhaust valve cant seat properly. Good spark from coils, injectors are working fine, and no vacuum leak I can detect. Hopefully, I didn't cause any damage driving it the other day...will know more later. Thanks.

Why no BTR dual springs?

The 8019s are dual springs and generally pretty reliable. I'm running a stroker cam with a .600 lift so I'm certain given the age and strength depletion over time, nearly any spring would have given up the ghost. I'm just glad I've been on this forum for a time now...made diagnosis pretty easy 😁

Damit, could have been worse though. So your telling me I need to swap out my titanium bee hives after 50k or so to be safe?
