Useing a Summit 6401 cam. .488 lift
About this Mopar:
These heads were just rebuilt to stock specs, before I bought them. So all I need to do is set them up for heavier springs to fit the Sum6401 cam.
These are the stock springs.
I'm liking this style compressor!
Made up a valve organizer.
The stock valve guide bosses.
Checking valve retainer to valve guide clearance.
Checking installed height.
Doing the math. (Don't use these numbers)
These are the cutters I'm useing.
Cutting the spring seat.
Checking the spring cup that I'm useing.
The cutter doesn't work too bad by hand. You need a heavy amp. 1/2" drill that turns nice and slow. (Tends to chatter at higher speed)
Useing the valve seal cutter. Once you get your height, just stack some washers for a stop under the cutter.
That's it. Not too bad of a job. The hard part is figuring out the valve spring that you need, the parts that will work with them. The math needed to make it all work.
