In machine shop, do this frame only if cylinder head is
t a g g e d for resurfacing.
If cylinder head is not tagged,
go to frame 19.
No more than a total of 0.005 inch can be machined off
g a s k e t surface of cylinder head (1). If cylinder head
h a s been resurfaced before, amount of metal machined
o f f is stamped or etched on front of cylinder head about
1 / 2 inch from gasket surface.
I n machine shop, resurface cylinder head (1) until no scratch or gouge is
d e e p e r than 0.001 inch. Resurface cylinder head until it is not out-of-flat
l e n g t h w i s e by more than 0.005 inch or out-of-flat crosswise by more than
0.003 inch. If more than a total of 0.005 inch must be machined off to do this,
g e t a new cylinder head.
If old cylinder head (1) can be resurfaced without
machining off more than a total of 0.005 inch, do step 2.
I n machine shop, add amount of metal just machined off cylinder head (1) to
a m o u n t machined off before, and stamp or etch total on front of cylinder head
a b o u t 1/2 inch from gasket surface.
M e a s u r e thickness of cylinder head (1) from gasket surface to bottom of valve
s p r i n g counterbores (2). If thickness is less than 3.365 inches, get a new
