Even a 235 head gasket should inter-change with a 261. You NEED a 261 gasket,because the 261's head/block, incorporate "steam passages",for improved cooling.This,however wouldn't cause the problem that you have. Did you have a head gasket leak before you replaced the gasket? Could it be possible that you may have a cracked head?? If your gasket doesn't align with every bolt,oil,and cooling passage hole,it's NOT the correct gasket. Find the correct one,and make sure all mating surfaces are CLEAN!! Make sure you follow the torque sequence. Did you check each and every bolt,to make sure they're torqued to spec.? This could cause an internal leak,as well as lack of pressure. Make sure to re-torque after engine has warmed up,(at least 1/2 hour @ idle). Follow the advice,in the "Links" section,on how to "adjust them valves". Two settings of the train,adjusts all 12 valves! I tried it...I LIKE it!! I had a hard time doing it with the engine hot, though. by the time I got done,I had several blisters! you can adjust them with the engine cold,as well. give yourself an extra .0002/setting,to accomodate expansion clearance. Hope this helps!!
