after warm up temp hand goes to hot for 20 to30 secs then back to norm, meanwhile heater blows
cold, coolant blown out of reservoir,put 2 new
tstats & 1 new tsensor but no help, coolant is not hot this can happen 3 to 5 times then engine temp
runs normal until vehicle parked and cooled then it starts over again could this be a blown head gasket
or what do you think it is

Very possible a blown headgasket

do a headgasket test
I would make sure it full of coolant and no air pocked in the system
