Correct me if I'm wrong or this has already been said, but you would want SOME roughness in the intake tract for tumbling, wouldn't you?
There's multiple schools of thought on that. Some people leave the floor of the intake ports rough, to get that tumbling effect. I personally smoothed them all out, because I'm doing a tiny bit of re-shaping. I'm attempting to use the Lovell effect to achieve that same tumble, while still getting the velocity increase from having the ports smoothed over. It's really up to the guy who is doing the work. I've seen both ways done, and I've seen both ways achieve significant power gains. To each their own, I suppose.
So here's the progress from last night. Those last 4 exhaust bowls to the far left of the picture (front of the engine) are all that's left to do up top here. I should hopefully be able to get that done today, which will allow me to start on the gasket matching while I wait for my finishing buffs to come in. I still need to order those, if anyone has suggestions. I was leaning towards the Dremel bits that are basically little scotch-bright pads, but I'm not against using cotton and black emery rouge, either. Once both those things are taken care of, it's just the combustion chambers and lapping the valves, then I can start gearing up for reassembly.
Has anyone taken the time to degree their camshafts on a factory rebuild? If so, were they able to be adjusted? Or is it something where I'll HAVE to buy adjustable cam gears?

Just ordered some stuff off of Amazon, and it'll be here tomorrow. I love living in the future
. I got a 20 count of 240 grit triangular cartridge rolls, to get into the few tight spots the drums can't reach. I also got a 20 pack of wool/felt buffing wheels, to go with the few that I still have from one off the giant boxes of Dremel bits I picked up at Harbor Freight forever ago. Lastly, I got a 1 pound bar of black emery rouge to use with the buffing bits. All of that, plus the 5000 grit wet/dry sandpaper I got to finish off the combustion chambers...this head is going to sparkle when I'm done. It probably cost me about $100 in consumables to do the whole head, which isn't so bad. It's also cost me about 60 hours of my life so far, and I'm not even close to done yet. That, well that is a little bad lol.
