Another Valve Job Question...
 

I think this has been asked many times, but better safe than sorry. Since the rule in Stock now states "any three angle valve job permitted" does that also mean the seat cut can be any width or are there still limits? What about top/bottom width limits?

It is my understanding that you can get as stupid as you want with the VGS20 but there are two cautions. Any cut in the chamber must be piloted off the guide and be careful with the bottom cut as there is a max CC on port volume. I think the current rules were written to take the tech guy out of the creative valve grind evaluation business and give him a more concrete platform from which to judge. That being said, I wouldnt get too carried away; it is still possible to make stocker heads into landfill and get a nice vacation from racing with the deal. TT
