Re: RIP WBX
Judging by the chamber shape, in the above pics I see sunk valves here.
For comparison, side by side
Sunk valve and stock valve chamber, the German stocker is 18cc and bigger in chamber volume than often quoted, they came from a brand new factory MV 2.1, suggesting to me they supplied the bigger chambers on MV motors, other heads I've CC'd, have been only 14cc.

Re: RIP WBX
They go right in with no machining, normal common sense applies to check for ovaled ends, if they go in loose, the rods are fretted and a throw away, ive had them were the cap just falls off the bolts, scrap them, there's nothing wrong with new 2.1 stretch bolts either, just stretch them 003" and done, usually that's about 30/32 lb/in.mr horsepower wrote:Do you guys machine the rods when you go on arp s
