I just bought a set of 990 heads for my 468 build just wondering who all runs them. Mine have 2.25/1.88 valves, ported by a guy in Bay City. Good or bad heads to start with??

Did they work good for you, what did you have them on?
i used them on builds they work .there is more to it then the heads .Rpm . Cam. CR. intake . cfm +heads . to make it all work .not just one part
Oh ya for sure, there's a lot more to engines besides just heads.
