Default 408 Question

I will be doing a 408 soon, I plan on running a FAST 90/90 and I will be spraying on it as well. Which heads would get me the most power for that set up?

Default heads

depending on your budget, any of the aftermarket heads will work well. ETP 4.0 bore LS7 heads with the LS7 manifold have had no problem making 550+ at the tires and will carry rpm very well. If you are set on using a fast manifold, most of the afetermarket heads will be close and are all in the same price range
