i have been driveing the car now for about two weeks and noticed that the radiator hoses have alot of pressure in them but the car dont over heat . i drove it last night for about 15-20 miles and came home and the top radiator hose looked like it was going to pop but the temp gauge was only about a 1/4 of the way up .the set up is a sleeved ge ls block 84mm ,b16 head,arp head studs ,civic 2 core radiator ,pusher fan . a local guy said that the head gasket could be put on up side down but i put the motor together and know its on right does it sound like a sunk sleeve or a blown head gasket .
