Cylinder head flow - What is crucial in a stocker?

[Rob Petrie E395]

Earlier in the thread somebody mentioned price. I bought my heads from another racer. So I don’t know. But is that accurate $5,000 for new stocker heads and $1,800 for an intake? And is that assuming you supply them with good cores to start with? I’m just curious. If you think about it. Even if you knew how to do it and what do do. By the time you bought all the equipment to do it. You’d have to do probably 100 sets of heads or more to break even on used equipment. So in the end for most of us it’s still cheaper. Although expensive. Plus you theoretically get all their R&D as things advance over time. Again I’m just curious at some point I’ll get a new set. But for now these ones I have will have to do. If you don’t want to say here. Feel free to PM me.
