I spoke to the place in Maryland today. He did not think that the mushroom
cam/lifters was an idea he would like to see in my car. He suggested that I
use a flat tappet cam. Guess he thought the $$$$ for a roller would not pay
very big dividends. Had some interesting ideas about many things, many of
them seemed directly apposed to what I have come to feel is the norm. One
thing for sure, I need to make things as sure as possible with this part of
my upgrade. Toooo many benches full of parts. Toooo many new changed and
untried systems on vehicle.

Anyone have opinions of roller cams vs. flat tappet?

Other than the dollar figure, I thought rollers had thing covered hands
down!
