purchased a pair of edelbrock heads full cnc stage 3 (60779 S3) from hughes engines back in
2012.looking at doing a cam upgrade and have lost the flow sheets,have contacted hughes engines but they are unable to provide me with flow sheet as they do not keep old data. Can anyone please help with some flow sheet pics.Please note their current 60799 S3 heads flow numbers are different to the 2012-2013 ones.
