my first engine rebuild (318) advises

Measured my heads today.
Used medical syringe and deere hy-gard oil.
got about 66cc on both heads, Maybe heads have been milled someday in past.
I found shims under valve springs when i removed them, about 1mm thick.

So i put all my info to compression calculator and got compression 9.528.
dynamic comp is 7.835 if i put 10200701 voodoo cam on it.


My old comp was about 8.5, so thats one point up.

Trying to get engine to machinist next week, to make sure i get correct pistons, right size bearings etc, and to see if i need heads worked.

Funny thing hy-gard oil didnt get past valves, and there were no springs in place i just dropped valves on:)

Oh and funny thing exhaust valves weren't burned from the saft like i first tough, that was just some carbon deposit :)
