408 build questions

Since the valve isnt being lifted very high... Save money and bowl port the stock heads W/a comp valve job. The Edel. Heads are nice but the cam spec do not take advantage of the better head flow the Edel. offers. If you change your cam out with a higher lifting unit, the Edelbrock would have been my choice.

Remember that the duration (while letting more air and fuel in for more power, it does) dictate(s) the RPM range your engine and car operate in.

Even the Edelbrock heads can use some extra port work for a 408.
