Hey Joe,

what's the deal on the VW rods you're planning on using? Lighter, stronger, cheaper? Haven't heard anything about those.

Joe, what does "lapping" the vales mean. Also having the block decked? Explain the terms, We don't use them here that I know of. By the way,havn't seen anything in the mail yet.

Lapping thats a hand valve job, if the sealing surfaces are not straight, use new valves.Use the coarse lapping compound then fine lapping compound.By smearing a bit on the sealing surface then pressing the suction end of the lapping tool on the valve face you turn it
lifting the valve every so often until you get a even matt color in the compound.
Do it again with the fine com. after cleaning up the coarse untill you get a dull color. Done lapping the valves.If your valves are not sealing up.

Decking & milling are used to finish the cyl. & block. It was once used by hot rodders to raise the comp. On a porsche motor this is only done to ensure everthings flat.Decking of the block does that and bgings piston height to its correct height.
If on a 944 you blow a head gasket and dont check the head for warpage you stand a good chance of having it happen again.Only have enough mat. removed to correct the prob. removinf to much will cause warping and static timing problems.
