Has anyone here used Moderncylinderhead.com for porting work? My buddy just got his 5.3 LS1 heads done up by this company. They put a head/cam package together for him, which yielded 450whp on 93 octane and stock bottom end! I thought about sending a set of heads to them to see what they can do. Just wondering if anyone has used them before.. Also, which cams are you blown guys using?
