I have decide to build a head for my 855. I found a 1999 v70 N/A head at the junk yard. I have read these cams have 8.8mm lift. Well the cams are the same old N/A 8.45mm cams. The good nws is that it has ME7 ports with beehive springs and there is room between the head surface and the exhaust ports to drill coolant holes to use the s60r MLS head gasket. This looks like it should be a huge improvement over the 850 head.
