im looking for the maximium allowable measurements for the 22r head, to seal on a new gasket.
my 22r was overhead and driven with a blown head gasket for....an unknow amount of times.

in thousands of an inch....whats the max im allowed to get away with?
ive googled the question...but found nothing.

thanx

IMO none is acceptable. But I am sure that spec is listed in the FSM.

i agree on zero being accepted as allowable,but ive picked up a new head years ago with 0.02 ths gap in the center,installed,car ran fine for 5 years till it was totaled.

forgive me for being so....newbish....but what is fsm?
factory service manual?
i have the haynes manual,but cant locate the specs.

yes FSM = Factory Service Manual. Try one from here: http://www.ncttora.com/fsm/
Personally anything that has more then 0 warpage I would fix before putting it on. Cheap insurance.
