Damn , so what started that chain reaction?
Livernois heads?...
Damn.. hate to see that. What springs were those?
I had to hog heads out quite a bit to get the Manley springs to fit... They were rubbing on the newer 08+ heads where they fit the earlier heads. I plan on asking Michael to keep the cams to around .550 lift to avoid things like this
Yes. I've have had two sets go thru my hands of the first batch of new cores with 12mm plugs, both sets leaked thru the guides. This set being one of them, then mine and then another driver's head I received with a broken cam cap due to improper packaging, so that adds to 7.500$ of crap.
Now, the breakage doesn't have to be related.
The ones that Livernois provided, that initially said they were .600 lift (but they won't go much farther than .550).
After you have your engine running for some miles, I suggest inspecting them so you may catch possible issues before something like this happened.
I did wanted to remove the heads from the car when they were smoking and switching springs at the same time but customer said no, we would have catched this before happening, now it is too late.
We installed my engine in the car and now I am looking on what to do with all that is left.
