==Are steam holes needed?== [[File:Steamholes400.jpg|thumb|200px|Showing approximate angle of intake side steam holes]] [[File:400steam holes deck.jpg|thumb|left|400px|Click on image for enlarged view]] There are quite a few builders who claim the holes are not needed on an engine that will see "normal" duty, i.e. not idled for extended periods like a delivery truck, for example. Among them is noted engine builder [http://www.speedtalk.com/forum/viewtopic.php?f=1&t=30647&p=363026&hilit=steam+holes Joe Sherman] (of Joe Sherman Racing) who says, "I have built hundreds of 400 engines, WITHOUT the steam holes, and never had a problem. Guys used to send me their heads for me to drill the holes, because I only charged 80 dollars to do the job, but I never did it for my own stuff."
