In this episode of Tech Lab Tuesday, David Vizard shows how 21st century porting technology can really make for outstanding results. The heads in question here are the double hump 186 head castings from the late 1960's and early 70's. The techniques involved here can be applied to all 23 degree SB Chevy heads as well as many non Chevy heads.
Thanks again to David Vizard for graciously allowing us to share his expertise with our Goodson customers!
