After having the F word Brand truck for many years and many blown engines making the change was eASY. I AM JUST CHECKING TO SEE IF THERE IS ANYONE WHO HAS HAD ANY HEAD BOLT PROBLEMS AFTER PUTTING THE GIDDY UP TO THERE 5.9. Was also curious what EGT's people were seeing under power.

 

I have put down over 600 with stock polts and over 50 pounds of boost with no problem. I do have head studs which are pretty cheap insurance for these trucks.
