Making power out of the 318

I have 1 problem with the speed master heads idea. And it's a huge one. Aren't they made in China??? I'm tired of this.
When I built my last engine (which happened to be a/6) I bought a good majority of my parts here and there from eBay, new parts but "dusty boxes"
partly because I got them at a great price but partly to avoid the China deal as much as possible. And it was actually easier to find much of what I needed for a better price. Much of what was needed I couldn't even find locally.
It does take some looking around there though. What you might need, you might not see today, but it might pop up tomorrow. And the first example of what you are after you can't buy. Put it on the watch list so you can find it later if needed.
I've seen too many times where the 1st one that popped up (of whatever you were looking for) might be $150. The next page down that same exact thing is listed for $40.
For the cam I sent my original one to Oregon for a regrind. As well as bought my lifters from and my valves too (SI brand oversized)

Also, I do all I can with stuff I already have.
