Does that mean that they're shinier now than they were?


damn it, I tried to post a clever gif but I think the dork forum adim doesn't allow it so

Duh! :lol:

They were a satin before....scotbrite with WD-40. this is a dry buff which shows the sanding marks more but is glossier.

Well...the lifters look like shit. No similar issues with the cams that I see. I can lap them clean.....not sure I should....hmmmm......it's about a grand I don't have to replace them.....always something.....

Why that happened to to teh lifters remains. I spent a bit of time reaching out within my little circle this morning and the focus is on the fact that the valves were all hitting the pistons a bit as the most probable cause. With that fixed (which I will confirm by claying the pistons once the block and crank return) just cleaning these up and reassembling should be fine and certainly they will survive until I pull the cam covers to check the head torque and valve lash and then I either smile or replace them so very little risk and valves hitting, metal in the oil and not enough cam lube will all have been eliminated as possible causes leaving they were never good parts to start with or something more to do with hardness or surface finish mismatch with the cams. A couple days of lapping for me I guess.

They are hard. I can't mark them with a screwdriver. I did the first one by hand and it took about 90 minutes. The next 11 I cheated and "lapped" on a running DA sander. I get 2 at most from a sheet of 40 grit, then 2-3 with the 80 grit...very light, they barely get warm. Then spend about 10 minutes by hand 100, 220, 600. Maybe 20 minutes total. so I now have 12 after about 5 or 6 hours total time...so paying by the hour it would be WAY cheaper to just replace them, but currently I'm time rich and cash poor so lapping it is. A very big vodka drink helps.....

with 1 set of buckets done I decide to take a break from lapping and do the shimming....these l9.5mm motorcycle shims are so cute and light compared to the 30mm(?)  ferrari shims

Finished all the buckets and shims on head 1. Decided to shim a little looser than last time....the software likes the intake at .011 and exhaust at 6 or 7 iirc....then the cam grinder said 8-10 intake and 10-12 exhaust. I decided to go with what ever the looser number so 11-13 on the intake and 10-12 exhaust. If the intakes are making noise I'll go a little tighter next time the covers are off...but the intake has very long accel/decel ramps so tight costs a good deal of bottom end power....or so says the software

They say 2 heads are better than 1...so 2 it is

I had to steal a couple shims from the 1st head to finish the second as most of the stuff I offered to top up the kit didn't arrive, I'll replace and double check when they do arrive.

So now it will be busy work until the black and crank come home.  There are some little scratches on the cams, I'll polish those up a bit.  The headers could stand some clean up...wires laying under the dash.....I'm sure there's more.
