Don, I've just ordered a Scott Brown solid flat tappet stick for my 493 build - with flat tops zero decked for about 11:1 CR. Comp Cams recommended a flat tappet cam for street/strip use as well, as they said it's not as rough on the valve train. This was based on as much as 1000 miles a year including street driving and some time at the track. I should know in the next month or so how it's working out, I'll let you know. Jerry
