Default THIS is why you mock up b4 you coat aftermarket headers

I bolted up the headers today, used Hookers that came with the car. They fit good with the Dart Pro 1 heads-just couple trouble spots, one is by the steering linkage which the primary had to be "persuaded" a bit and another issue is with the #4 spark plug, it's too close to the primary and needs to be clearanced. I will have both these spots cut out and welded in smooth bends before I bring the headers and side pipes to be coated.
This is why you do mock up "B4" you coat, hehe

That's actually pretty good compared to how my Hookers fit with the angle plug AFR's. Very smart to take the time and effort before sending them out

Here is my #4 after being "clearanced"

I assume so you don't strip out the threads in the heads.

1. You won't strip out your aluminum heads

2. Ease of remove and replace headers. Just hang the gasket and slap on the headers.

3. 1 3/4 inch pips are very close to the bolt head and these little 5/16th ARP nuts give clearance.

4. They never back off our get loose.

5. Because I said so!

IMO, you've got adequate room to the #4 spark plug.

No need to cut and weld

Get a large socket, like over an inch. Big.

Toss a towel maybe with a fold or so on the tube
Lay the socket on its side
With dead blow hammer or something similar strike the socket at a very slight angle, it will slightly flatten the area without bashing it making a clean job out of it and no chips in your coating.

Don't they also make shorty header plugs ? I'd happily trade my BB headers for a pair of 69 stock manifolds, any takers ?
