Default Headers Arrive

Today I received my headers. I posted a couple of weeks ago that they were done, and they are now in my grubby hands. Initial thoughts:

1. They look well built and are substantial. The flanges are 3/8" and they weigh 30 lbs (these are the 14 gage version discussed recently). General quality looks good.
2. They seem pretty compact, but I have not held or used another set of pontiac headers.
3. The welds look OK (not show quality, but strong enough to last a long, long time). There was some cleaning up done to the welds to make sure the headers had no spatter.
4. The ports are welded inside and hand finished, and look pretty nice.

The headers took a while to get here because they made a quick trip to a dyno, which also explains the blue tint to the headers. I am reviewing the dyno info in detail and posting in a couple of days.
In a non-optimized dyno test, the headers were within 1 hp and 1 lb ft on peaks on a 575 hp, 461 stroker when compared with a set of 1-3/4 super competitions. Again, details will be posted within a couple of days.
Many, many thanks to Dave at SD Performance for squeezing in the dyno test in during a very busy time of year.
