Edelbrock Heads Sound Like They're Terrible

I tell my customers this time and again. You will have $2000 into a set of plain old RPM heads to make them a GOOD usable part.

Some of the other things not mentioned are the bad valve job, horrible core shift, tight guides, cheap springs, cheap valve seals and I have seen my fair share of metal shavings in them.

They do perform well, but it takes some doing!
