I have a '99 4.0L with high mileage. It runs strong with 'normal' leaks and no smoke. I have been looking into Cleggs engines for a stroker kit when I am able to do so. My head on the other hand has knocking valves and this is where I have questions.
Expect for tearing the top end of the motor off, would there be any other downside to putting a new head on now, being that a stroker is not in the near future?
Also, I like Clegg's Stage 3 Ported head that I wanted to mate with their Stage 2 Cam kit. What will I need to do to get the most out this?
I will also be replacing the exhaust.
The head and cam info are at the bottom of the page:
