Those who do your own cylinder head work, what are you using for valve bowl/pocket hog tools? What's reasonable and won't put me in the poorhouse?
I have an old B&D in great shape and make my own stones out of blanks.
simple Dremel. It's all I've ever used.
The very reason I like a Dremel. It doesn't gouge all at once like a air grinderyeah well.......I just ain't "that good" with a hand held. lol

I have a Souix set, and that what I do, because I don't have a Winona or equivalent guide and seat machine.That's sorta the direction I wanna go. I got no problem with stones. As long as they're dressed and the pilots are tight, you'll get a good job. Just right now, I haven't found anything affordable for me. Maybe somethin will come along.
I have knockoff dremel tool, but attachments are friggin pricy. I've checked walmart and limited supply there. Suggestions?I have an old B&D in great shape and make my own stones out of blanks.

Good quality carbide burrs run about $40 each but will last a long time on cast iron if you don't overheat them and chatter them.Brian can you explain what you mean by "make your own" ?

I think what he means is that you buy a straight (solid)cylindrical stone of the approx diameter of the inside of your valve seat, then diamond dress it to say 75deg(7.5degrees off of each of the straight sides) until it is a cone shape with the smaller diameter end, the approx size of the bowl throat, and grind away until you're satisfied. I THINK that is what he is referring to.Brian can you explain what you mean by "make your own" ?

Yes, Not necessarily hand porting.I think what he means is that you buy a straight (solid)cylindrical stone of the approx diameter of the inside of your valve seat, then diamond dress it to say 75deg(7.5degrees off of each of the straight sides) until it is a cone shape with the smaller diameter end, the approx size of the bowl throat, and grind away until you're satisfied.

I use Dremel stones like the 8193 stone made by Dremel. I don't like air tool cutters because most of the time they gouge too fast.I have knockoff dremel tool, but attachments are friggin pricy. I've checked walmart and limited supply there. Suggestions?

Yep. There's a certain amount of consistency there until the stone wears down and needs dressed.So using the grinding stone as a form cutter to shape the bowl walls by plunge cutting? Yikes! Better be rigidly mounted.
It's interesting how stable the 6" long carbides are. I thought they would chatter all over the place. I think you don't force them too much because of their length.HF electric die grinder with carbide burrs (mcmaster carr) and router speed control. Dont know that I have much more that $150 into it all.
Make a fixture to hold the head firmly in position. Slant six rocker shaft works and allows it to rotate.

Dont like to disagree mike but i just bought 2 of the long burrs single cut for only 16 bucks each from mc master carr.Good quality carbide burrs run about $40 each but will last a long time on cast iron if you don't overheat them and chatter them.
Dont like to disagree mike but i just got some from mcmaster good quality ones to, 1 was 16 and 1 was 20.Good quality carbide burrs run about $40 each but will last a long time on cast iron if you don't overheat them and chatter them.

It is. I would do that no other way than to use the proper fixture that mounts to a pilot that fits into the valve guide. I am also looking at carbide cutters.
I have a Souix set, and that what I do, because I don't have a Winona or equivalent guide and seat machine.
But I have to warn you, when you are using one of those slightly tapered stones, they tend to want to seize in the hole, kinda like ball joint stud tapers seize/ lock-up. Boom, the stone explodes. As long as you're wearing safety glasses you should be good, but the first time it happens don't be surprised. Just be patient and don't lean too hard on it.
Even w/a rough stone and a pilot, the bowls aren't uniform, I have carbide pilots that are hard & accurate...but if Your not patient(VERY) the side loading can snap them. That goes for stones and multi-blade/bit cutters, but really for single cutters ie Serdi etc. If You lay out Your dimensions accurately on card sheet, and set the width/height w/markings starting from a guide center-line, You can exacto-cut a template out and insert it in the guide and work with a burr till You're really close. Have You used/seen the ones Mopar sells/sold?It is. I would do that no other way than to use the proper fixture that mounts to a pilot that fits into the valve guide.
