Your Opinion and Suggestions please.

It's just that Edlebrock's have some issues with there QC and some things need to be addressed. But most anything that you will do to a stock as cast port will help, by this I mean removing any sharp edges and radiusing, then narrowing up the valve job that comes with the heads will be a plus. This will help to increase the flow at low lifts and help mid lifts also and this is where you want the heads to flow the best. Most cams that are in the range that I posted will be in the .550 -.600 range and all the flow you can get up to .500 will be best.
