Cam plug leaking. Removal and replacement?

I put some more thought into your cam plug business. Not only is it in backwards But it's still wrong. Your block is a '72 so it takes the concave cup style plug like what Toolmanmike posted earlier. The "step" where this plug goes on the earlier engine is .225 inch, the later engine the step is .385 inch. Concave cup size is 1.875 inch.

Thanks for the heads up Max1196!
SGBARRACUDA was so kind to send me one, I got it today, but left it in the car and will have to see which one it is in a little bit.
Roy, pm me your email so I can reimburse you.
So if it's the new style I still need to find the correct one, no biggie. What a nice gesture, though.

Got the heads and intake shipped out today. $120 for shipping Fedex, TX to NC, insured for $1800. Local UPS store wanted $160 for a single 85lb box and over $200 for three separate boxes...WTF?
