Question for Cylinder Head gurus

In March or April they changed vol. of X's to 167 from 160 after a LARGE argument and much name calling (most has been deleted) about port volumes on this site.....several folks telling me where I should place them. NHRA has all volumes on website. J's are 160 or 158 depending on valve size I believe. I have several HUNDRED small block heads in storage. If anyone want to compare difference first hand...... you welcome to come by to look and compare at Vegas Nat's or Div. There are significant difference in port shape and configuration as well as combustion chambers.

Aspen 7709: Careful about too much advise please! Lets keep a little under our valve covers.

LuvMopars: You are welcome to E mail me for more advise in private.....you already have my address
