I've been using a pushrod checker to establish my length. I've been through pretty much all possible sizes, and anything above 6.500 puts it way off the tip of the valve, so I was getting pretty worried because thats what I thought alot of guys were running. I think I'm pretty close with what I'm running now, although I agree its a bit on the short side. .100 longer puts in just a bit too far over the centerline on the exhaust side for my liking. I think I'll expand it .050 and see what I come up with. The sweep length looks OK to you guys?

Thanks for the help
