In this segment Dan Begle from Mahle and Billy Fisher from Straub Technologies dive into the secrets of porting cylinder heads and port matching to produce more horsepower.
Billy and Dan share some well-learned lessons on the magic ratio in seats and valve guides, how valve angles play into RPM, and why bigger is not always better.
They also provide some great tips and tricks on everything from using snap gauges to make sure ports are equal to matching gaskets over ports, and how to get a manifold and head to line up with a gasket in between.
It’s a super-informative segment you’ll probably want to watch a couple of times to catch all the information in it.
