W2 head porting observations help needed!

W2 heads are a very nice head and take about 1/3 the work as an Edelbrock head to hit 300cfm. I kinda soured on them when mine cracked. I the sold off two and a half set of rockers and the W2 Victor intake I ported. Years later I bought a set of W2 race heads with Norris rockers and an intake from a friend and sold it all off making a small profit. Should have probably kept them.
