iron performance heads for SBC
Is aluminum the only way to go to have some really good gains from a head upgrade? I mean aluminum AFR's, GM Fastburns, Edlebrocks all cost $1000-$1250.
Is there no equivelant flowing head with @200CC and 2.0-1.6 valves that are affordable? Whats is anyone else running? <img src="confused.gif" border="0">
