To make a long story short, I'm getting some MACs finally thanks to a GP through Jet-Hot. Well, I checked on the board and seems a lot of folks really like the 1406. Well, someone posted some pics of new coated MACs not too long ago. I looked up some Fel-Pro's for my car (94 Z) off Pick Pro Parts.com and the ports look like they would fit better. They are more angled. Pics of the 1406 show a more rounded exhaust gasket. Anyone had any trouble with the 1406's? Any trimming involved? Thanks.

 

Ive always used the stock GM metal gaskets with my Mac's and theve worked great!

I second that.

 

Thanks for the replies. Anyone else on the fitment of the 1406 on Mac's?

 

Any more insight?

 

Trust me man, the GM gaskets are the only way to go, I've only tightened them down once, did a trip to Sonora, about 120miles, drove around for 3 hours, let the car sit in 30º weather, get it hot, repeated about 5 times, no leaks yet.

 

Do you have a part number for the GM gaskets?

Thanks

 

I have a brand new set for sale now. I just posted it on ebay a few hours ago...But, Ill end the auction if you want them. Ill email you a pic in a few min. Its halfassed, I had to scan the two sides and paste them together. Youll have mail in a few min.
