Have you got the Part Number for the block?

With that we could help more.

It also helps to know when it was NEW. Some of the more recent R3 blocks have gone to a more generic set-up when delivered.

BUT count on at a Minimum
1.Line Bore cam Tunnel (50mm-60mm Bearings are about $90-120/set)
2.Line Bore mains
3.Bore and install Lifter Bushings
4.Bore & Hone Cylinders
5.May have to drill for oil filter if you want an oil filter on the block. some come with a Blank Non-Drilled oil filter area.
6.May have to Deck the surface to true it up.
7. Lifters are from Comp Cams and Morrel usually about $600-750/set
8. Cams, you'd be best spending the money and getting Bullet or LSM to cut you a billet one.
9. Tube the lifter valley to force oil drain to the back?

Far as the W5's??? Not that familiar with them.
