Broken head. (56k warning)
Broken head. (56k warning) A little backround. Heads & cam have been in for around 4k miles. Along with heads & cam were PRC dual springs, chromemoly pushrods, new lifters & ported ls6 oil pump.
I had just pulled out of a gas station & was driving normal. Speed was about 45 mph. The car revved up 3-4k rpm, I let off the gas & put it in neutral. The rpms & mph kept steady even after letting off the gas. There was a squeaking sound for a few seconds along with loud tapping and a pop. After that the car died.
Now for the pics.

No worries man call me on Monday morning & I'll replace them with a set of the all new smaller runner ls6 heads. I'm making sure & swapping out any of the old none welded casting guys to the all new ls6 head if they have any issues.
The new ls6 & new 5.3l heads have never had one failure so we'll just swap you over so you'll be good to go.

That has to be the old version of the head, I redesigned with the smaller runner for better throttle response & to eliminate the possibility of this happening.
