I'm getting to the age where I have to calculate the time factor into what I do; when you consider the age of the castings we are using and that they usually require guides, seat work, studs pulled, bosses cut, surfacing and at the very minimum bowl blending and port matching....thats a lot of hours that I could better spend on other things....a pristine casting that didn't require all of that would be welcomed....those of us who have been at it awhile will probably get black lung disease from all of the cast iron in our lungs anyway....fats
