Summit sells TWs that have been CNC'd and they supposedly out perform the AFR 185s. But they are like $1600 or $1700. If I had the extra money I'd definitely get those.
Yeah, that's very pricey. I'm not sure whether or not I should port them now, or just run them out of the box until I do the rebuild down the road. I'll probably end up calling around to figure out the best thing to do with them. Any suggestions on where to get them ported?
