One thing I have become very aware of lately. A couple friends want my help porting there own heads. I have come to realize that grinding metal away is not very easy for people and you take that for granted. You have skills and tools that other don't so you cant make the claims you make because others simply can not duplicate it. It could cost someone else easily thousands of dollars to do what your doing in your free time.

But you cant go to the junk yard and get a set of heads that flow over 300cfm for any sb or bb mopar
