Headers

[oceangal]

I have to buy another set of headers and I am just about out of money with the car restoration and while I would love to get some Dougs headers or Hooker headers they are just too much right now. The ones I bought last year just aren't working out, something about the ports being too big and needing lots of welding and I would like to drive the car before the snow falls.

Anyway, anyone have these?

Sorry, I have Headman Headers. But they sure do look very similar except for the flange. I'm sure someone will come along to help.

I went with the Dynomax. They have been a popular choice here.

I have those headers and like them very much, fit was perfect and easily installed. Some NAPA stores sell them, that's where I got mine, but don't remember the exact price, that EBay price seems real good to me.

Not sure what kind of heads you have............plug clearance is sometimes an issue. When I first put them on my ZZ4 heads with angle plugs, there was plenty of clearance for plugs and wires. When I switched to Brodix IK-180 heads with straight plugs my #4 plkug boot is very close and will burn after a while. Even shortie plugs are too close, so a slight "dimple" is required to get a little more clearance.

I was able to find Dynomax ceramic coated headers for less than the ones listed on eBay. They fit perfectly.

This note kinda bothers me:

Breaking in an engine with ceramic coated Headers WILL result in damage to the coating and will VOID all warranties. Ceramic coated Headers require several heat cycles to fully cure before they will withstand extreme heat.

It only takes ONE heat cycle to cure ceramic coating (yes I have done this myself)...and they should have already done that. If they didn't then the ceramic coating isn't going to last.

The reason for that caution is that 99% of "first-starts" on new or rebuilt engines are done with retarded ignition timing during cam break-in, which dramatically increases exhaust gas temperature; add to that the lack of airflow over the headers, and almost any ceramic coating is taken beyond its design limits.

Yeah I can see that happening. I guess I just don't like the way they worded that...makes it sound like they didn't cure the coating themselves.
