I already took out the exhaust cam I'm trying to calculate the shims I need. My answers aren't adding up

You'd want a one size smaller shim .....on #1 for sure and #2 and #4 since you have it out.......Keep em in order ..... How does the center cam chain sprocket feel........mine had a fair amount of side to side movement but not rocking it......... be sure to clean and loctite the 4 screws when putting it back on (small center sprocket) not the cam cap bolts..... don't over tighten the cap bolts either around 80 inch lbs!! .....not Foot lbs!............. ......One smaller on #2 intake and one larger on #3 intake.

I'd leave the intake alone .008 ain't that bad and will tighten up over time.

I can't tell u how it feels the cam is taken out now I'm trying to calculate the shims needed for that exhaust that needs it. .076-0.15= -0.074. 265+ -0.074-=264.926. That's not right I need a smaller shim size.

Ok hoping you kept them lay'd in order........... check the shim for #1 exhaust ...... it should have a number stamped on it ....... if it says 260 on it you need a #255 shim which is one size smaller........ (a #255 shim is .002 smaller than a #260 shim) ...... if the shim number is worn off you will need to measure it with a micrometer to find out how thick it is and to find out what shim number it is.

After looking at my shims most of the numbers are worn off so

A 220 is .086.5 thick
A 225 is .0885
230 is.0905
235 is .0925
240 is .0945
245 is .0965
250 is .0985
255 is .1005
260 is .1025

He's talking about the idler sprocket between cams or where the adjuster is?
