I wouldn't go to DVAP, they just screwed me out of $80, because of my cracked head. I paid $150 for it, with shipping it was $178, the first 1, was obviously cracked, if they actully looked at what they pulled, they would have found it cracked, they sent me another, and it wasn't as visible, cracked in the siamese exhaust chambers, not bad, but too much for me, and I didn't find it until a little over a month after I got it so, they're agreeing to refund the cost of the cyl head, but not shipping it back. I'v got Memory lane searching for a head now, there gonna send them out 1 x 1 to get magnafluxed, so I'll get a crack free head ( magnaflux is my cost tho ).
