Flat tappet cams are abandon by most shops for yrs because of the roller cams do have that much better cam profiles overall.58cc seems small for today's gas.I won't get into imported heads and their shortcomings. [-(

The formula for most street driven cars is .5 x C.I.=175 cc intake runners.Really 180 cc is perfect for a 350/355.Skip White has been trying to make some in-roads that I have read about in the trades.One constant is make no doubt about it,you get exactly what you pay for.So the deals aren't.We resold god I don't remember how many used aluminum heads and everyone of them had to have valve guides.My point is they for the long term are not very durable.

The other thing is 220cc intake runners for the street on a 350/355 are going to result in a real saggy low end.

Hotrodaddy-I am just trying to just help out.
