Big Block Edelbrock limitations.

He really didn’t give enough info to even start in the first post other than saying they were out of the box heads. Lighter cars than yours but Thumper that rebuild carbs has gone 9.80’s with a ported set. A friend of mine in Pa has gone high 8’s in the 1/4 with his ported Edelbrock in a lightened Duster. It all comes down to the right package and how much you want to spend.

Well, I was trying to keep it as on point as possible. It's already veered off to converters, compression, etc. I do understand it's the whole package. So, if the untouched heads are good from 450- 500 hp (with my ok engine building skills), since I already own them, would I be better off both power, and financially, buying a different set of heads,say the TFS240, or having mine ported if I wanted to step it up to 550-575hp? For discussion sake, let's just assume there is no car yet. Just an engine I'm trying to plan out. According to the Wallace calculator, I'm only at about 400hp now.
