Hi everyone. Title says it all. I'm looking for cam gears that have the most adjustment built into them. Currently running skunk2 pro gears and I need an extra degree or two.

 

What have you done to your engine combination that would require MORE adjustment than what a Skunk2 Pro Gear provides ? What brand/size camshafts are you using ?

 

i curious too. My head is about decked .025” (close to max) and block maybe .010” and only had to adjust the cams about 2 degrees to get back to “true” 0*,0* I can’t imagine a scenario where you would need to adjust more than 10 degrees

 

Good questions! The issue I'm having is valve to valve clearance. Piston to valve is fine. When the head was rebuilt the shop installed oversized valves. I didn't request this to be done. I'm trying to run Pro3's and when I check v2v clearance I'm running the intake and exhaust valves into each other. No matter where I put the gear adjustments I can't get better than .030 clearance. I think that's a little too close.

I thought about seeing if the machine shop can cut the seats down a bit to have the valves sit "lower" in the head. But then the spring height may need adjusting. I don't really want to get a new head with stock size valves because this one has had a lot of work done to it and flows very well.
