Milling 225 head

casting#2843169 I cc'd @ 58.6, had.060" off & it came in @ 50. Had same off block w/a
set of stock .060" over slugs, deck over piston .130". With a printo-seal fel-pro @.039" it
worked out to 9.35:1, and actual cc'd w/8yrs. carbon build-up @ 9.469:1 .
Pushrods stock will be OK unless you add a decent lift cam (.470" lift NET & up), then
you may need shorter units.
