What About Edelbrock 340 Heads?

I have a pair of open-chamber Edelbrock LAs the machinist/builder said were basically only as good as factory iron in stock form, he ported them to flow 290+ cfm starting at 248 for unported. $1500 or so worth of labor but most of his time is spent porting and dyno-testing race BBC and turbo LS engines well into quadruple-digit HP so this was probably cake for him, fortunately he and the owner did it as a favor and even still I'm a tad over $2000 into the heads including purchase price, plenty of machining and parts (ALL new valves, springs, hardware). I haven't run them on the engine yet but they'll be serious, also post pics when I can.

In a nutshell... I think there are better ways to get 290+ cfm for $3500, probably less. I'd start looking at the new Trick-Flows tbh. Also don't go for other people's used damaged parts thinking you'll save money LOL
