Magnums VS. Eddy's

Use the iron ram 1.92 heads, as with the stock cam in the short block these heads will be the best benifit for your engine at the lift of a stock cam, and are very close to the eddy's out of the box. The velocity will be better with these heads than the eddy's will be also as the smaller valve and flow #'s show.
You could also use a set of LA heads with some work and get the same results with the 1.88 valves. And you would be spending about the same amount of $$$. But you wouldn't have to change the intake manifold and options will be more plentiful.
