Hey Lee, you might want to check out David Vizards "How to Build Horsepower
Vol.. 1". While it deals mainly with Mercian fire breathing V8 stuff a lot
of the theory and practice is covered. My copy was copyrighted 1990 and is
probably available at any good bookstore. Another source that someone on the
list mentioned a while back was Standard Abrasives web page. They have a
pretty good write up for "do it yourself head porting" They can be found at
http://www.sa-motorsports.com/diyport.htm One word of caution, don't go
crazy porting your head unless you have access to a flow bench. Porting your
head is a bit of a "black art" and it is very easy to reduce the power your
engine can make by "over porting" Good luck regards Craig Bentley
