How much smoke?

[Fox]

Well with the oil problems behind me and a few electrical gemlins worked out, my engine starts.

But very soon after the headers and what appears to the cylinder heads start to smoke. The temp gauge hasn't even started to move. All the wiring appears to be o.k.. Needles to say, I have shut things down to check it out. It ran for less than 2 minutes.

I know that some smoke is normal. Burning off the header paint and all the residues gained along the build process will likely take some time.

What has me concerned is the smoke from the cylinder heads. Specifically from the fore to aft passage through the middle of the heads. It occurs on both sides. I did take the time to check the valve train and lubrication does not seem to be the issue. These are aluminium GT-40 heads.

I guess I am a little nervous to fry things or do some real damage, so a little reassurance that there is or is not a problem would be appreciated.

Thanks.
