Yes I can agree that Macs have better plug access, but I honestly wouldnt trade the small difference in that area to sacrifice the potential, power, and coating that the RK's offer. My buddy has RK's that I installed and it seriously wasnt that bad to do spark plugs on. If you ever want to see them let me know, he lives in Boardman.

My buddy supposedly called RK Sport and get them from there @ $450. Not sure if that was a special deal or what? I'll call and ask him today and post back to make sure.

I was under the impression that the RKsports werent coated and that their identical twins, the Arizona Speed & Marine headers were the coated ones...maybe im wrong?

 

Both are coated. The AS&M claims their coating is better but after seeing both in person they look exactly the same. The ONLY difference between the two is that the AS&M have D primary ports and the RK's have oval. Is that a big deal, nope, but its a way to tell the difference.
