Cordes, for longer bits, get a piece of plastic tube or hose to slip over the shank. Now you have a protector on the shank and you can hold/direct the bit to help prevent chatter.

I made some more progress today. I've decided to make this set of runners pretty large. On the intake side they are 1.5" or better where the guide is so far as I can tell. I'm about .04" larger than the gasket width wise on the intake runner. I'm a little disappointed that I am wider than the gasket by that much, but live and learn I guess. I've raised the roof quite a bit, and put some work into the exhaust runner. I laid the short turn back some on the exhaust and lowered the floor at the face of the head there too. I'll probably try to raise the intake port some more, as the top drops down relative to the floor a little too fast as the floor moves toward the bowl. I haven't really touched the floor of the intake port with the exception of smoothing back the short turn radius.
I ordered some cross buff pieces and I will be giving those a shot next. All in all, this has been fun. I'm eager to give this a shot on an actual head and see the results.
the chamber work on this one . the relief. looks really good.
Thanks. I'm actually pretty excited to see what it will look like with the ports cleaned up. I was just hogging out a lot of metal today to see what would happen.
I gotta get an actual tool. I port matched my 2 piece lower to my phenolic spacer with a Dremel and that was a nightmare LOL.

are you doing that in the car? on the engine?
noting I've read here , or TD, turbo blankets can promote cracking of turbine and center housings ...
just saying , I have no personal basis for the statement
and I've seen my swing valve casting still glowing BRIGHT cherry red 45-60 seconds after a hard pull up the hill in front of my house
at the crest of the hill it probably would have been invisible from the heat in it
Where is everyone getting their cross buffs? I see prices all over the place for these things.
grabbed mine from amazon or ebay. dont remember.
they door burn down so get a 10 pack or more.

Thanks for the links. I'm having better luck on ebay than elsewhere.
Bottle brushes and buffs may mask undulations; files straighten walls.

"The sole condition which is required in order to succeed in centralizing the supreme power in a democratic community, is to love equality, or to get men to believe you love it. Thus the science of despotism, which was once so complex is simplified, and reduced . . . . to a single principle."
-- Alexis de Tocqueville
"One of the methods used by statists to destroy capitalism consists in establishing controls that tie a given industry hand and foot, making it unable to solve its problems, then declaring that freedom has failed and stronger controls are necessary."

"To evolve, you don't need a Constitution. All you need is a legislature and a ballot box . . . . things will evolve as much as you want. All of these changes can come about democratically; you don't need a Constitution to do that and it's not the function of a Constitution to do that."

These cross buff things are pretty amazing. I did a few hours worth of work tonight and was able to experiment with another intake runner. I have the roof pretty high, and I stayed much narrower through the port, which I think it by far the way to go. The next step is to make things even from port to port. That will probably be on the next junk head. After that, I'll be ready for the real deal I think.
Does anyone have a tool to knock the valve guides back into the head? I'm assuming someone makes a punch with a slave portion of the right diameter.
those cross buffs are awesome.
I normally have the shops do my guides. I normally have the locking ones installed. these things do like to drop guides now and then. especially on the exhaust side. at least for me.
