My 6.1 retrofit thread
Well..here we go - time to change the valve springs to something that will keep the valve away from the piston at 7000 rpm...
Pic 1 - Coils removed and one plug removed in each cylinder to let me rotate the motor - Then set it up on TDC. The empty plug holes are also useful to slip a piece of fine rod down, to check when each piston reaches TDC as you rotate the crank
Fit Valve spring compressor, screw down, valve spring, remove locks.
Unscrew compressor, swap out the factory Valve/cage, pull factory seat/seal, and swap in the new shims, locater, seal and spring in that order
Replace the retainer and screw down the valve spring - re-fit the locks.
Wind the valve spring compressor back out and check to make sure locks have seated inside retainer.
Pic 2 - rocker covers off, intake rocker gear is on the high side, exhaust on the low side......
