Welcome Back. Be sure to use the correct thickness gasket. A gasket that is too thick will drop the oil pressure because it increases the space of the cavity that the pump runs in. JMHO Stan

......Here's the gasket part number listed by TM Tractor. It does not show the thickness but it's very thin. Someone has said that it's about the thickness of a writing paper. Probably a search of this forum would tell the technical data. http://www.tmtractor.com/new/en/258fp.htmstephanev8brazil":1ipkvijd said:

Hi,
It looks like you are putting the head on the engine.
The head bolts need non hardening sealer put on the lower 3/4" of the threads before putting them in.
The bolt holes go into the water jacket, and water can run up the threads and leak out, without sealer.
Below is a pic of one product that works good for the head bolts, Permatex Aviation Form A Gasket.
It is sold at auto parts stores here in the USA. If you buy one, stir it before using it, it can settle in the can when sitting.
Below is a page from the Cub service manual, GSS-1411, showing the head bolt torque sequence.

I would read the engine section in the manual, if you haven't.
The manual is at the top of the page at Cub Info, then go to Rudi's Manuals.
Tighten the bolts gradually. I would tighten them to 25 ft lbs, then 35 ft lbs, then 45 ft lbs, each time following the torque sequence.
Before putting in the head bolts, remember there is a holder for the spark plug wires that goes on the 3rd head bolt from the front, on the right.
Below is a listing for it at TM Tractor Parts, with pics of it, if you don't have a holder.

Thank you, Indy61.
Besides putting sealer on the head bolt threads, here is something else you can do.
It isn't a necessity, if you can't find the spray there.
The people on here like to use Permatex Copper Spray on the new head gasket, before putting the head on the engine. It helps it seal well. Spray both sides of the gasket, just as you are going to put it together, and put the head on before the Copper Spray dries.
Use an even application of the spray on the gasket. Practice a little on some flat metal, if you have never used Copper Spray before. They sell it at auto parts stores here.
Before putting the head on, I would turn all the bolts in the holes by hand, without the sealer, and be sure they turn easily. Then remove them.
They have to turn easily to get an accurate torque reading. Use a tap in the holes to clean them, if needed, and a die on the bolts, if you didn't buy new bolts.
When it is together again, I would wait a day before putting coolant in the radiator and engine, it will let the sealers dry some. Don't run the engine without coolant in it.
Below is a picture of the sealer. Good luck.

I did make a new gasket with correct tickness. (0.004 inch) Thanks to Everbody for Helpping me.
