Power Building Videos Heads, Porting and Valve Trains
This triple DVD set has almost 5 hours of highly detailed information! It takes you step-by-step through the entire valve train, including many different types of cams (flat tappet, hydraulic roller, solid roller), lifters, springs, push rods, various cast iron and aluminum heads and much, much more. You'll be shown how to read a cam card, and how to degree a cam. You'll see what "lift", "duration", "overlap" and "lobe centers" mean, and how they affect your engine. You'll also learn about the different types of lifters, rocker arms, rocker studs, valve springs, retainers, locks, and intake and exhaust runners. You'll learn about installing larger valves, installing screw-in studs and guide plates, un-shrouding combustion chambers, gasket matching (heads & intake manifolds), bowl blending, what tools you'll need and how to use them. Aluminum heads vs. cast iron heads, what you can and can't run on the street, old wives tales and myths put to rest once and for all and MUCH, MUCH more!
