My 5.0 refresh is complete with GT40 heads, TFS1 cam & stiffer springs from Alex Parts.
I am not too sure about my roller lifters which I am reusing. Not sure what went through the Explorer 5.0 but all of the lifters have tiny grooves on them. I can feel it with my finger nail. The old lifters will not see double the spring pressure from 60 lbs closed to 120 lbs closed. I did take all of the lifters apart and clean them really well.
New set of roller lifters are $125.
What do you guys think. Should I reuse them?
