By the time you get done fixing the Ede's you'll be in at least $250-400 in correction cost. To get the ede's in the same HP potential range of the RHS head, it will cost $ to port them. Depending on the camshaft you use, the ede springs and retainers may need to go as well. It's all use dependent.
I have and are using some ede's and they are likely the last sets I'll buy. Never bought a set new, used and got them corrected, etc. so I don't have the cash outlay that some have when buying new. I have a current set that EVERY single bolt hole needs a heli-coil.... yeah that's fun! NOT!!!
They are easier to fix, if you say, lose a cheap rod and have a piston bang the head.
If you are going to compare products from hughes and what Brian offers, make sure you are comparing apples... The hughes super prepped ~1400, IIRC, which do not include springs/retainers are more in line with what Brian offers which comes with springs.
