Surprise! Now what...

Well the machine shop just let me know that to use the steel heads they'll need everything including seats. I guess a set of Edelbrock heads are going on the list. Is there a good alternative cost effective head? Notes taken on the need for flow.
So to those not impressed with stroking a 340 - what's a good alternative build?
Don't know about the others but my 418 stroker pulls strong all the way to 6000 RPMs
