thought they were. the old pro topline became southern performance after a management change. comp cams had their finger in the pie. they relocated the operation to china.
they were taking moulds off my Indy -1's when the order came thru to relocate. if comp cams hadn't done that we would have some more max wedge heads to choose from. all the uncompleted & r&d stuff went into the bin. they had copied almost every ford & chevy head available & were making improvements before they would make there own copy. there were some clever dickies in that outfit, shame it went to china.
