Edelbrock / RHS heads, or go BIG block and put it to bed!
Rumble, all these are opinions. No biggie. It's all about individual's experiences and knowledge. Those are all unique to us all so you get debate. No problems here. My single biggest complaint with Brian's package is he's in CA and I'm in CT nad these things weigh a ton. The shop I use will not be able to match his pricing, but add another $100 or more for shipping, plus the fact that it keeps my local shop supported, and I'll use the RHS when I need to.
RHS are not my first choice for weight, bling factor, geometry, or potential. OOTB (albeit valve job fixed on the RPMs and a good 5 angle valve job like Brian does) flow wise the RPMs are the RHS equal, have more potential down the line, and are a bit lighter. I stand by my opinon. As Cracked stands by his. And like he said - it's all good.
BTW - Do some research into why heli-coil thread inserts are used. They have much higher strength than the base metal. That includes iron, BTW. OEMs dont use them unless they have to because they are more labor intensive and expensive compared to designing in a longer bolt or finer thread pitch where needed.
