55-65-(70-75) In the correct sequence. This applies to the late 60's through the early 80's models.
The cylinder head torque settings for a Land Rover 300 DTI starts at 40Nm for all bolts. Then for M10 x 117 mm long 60 degrees, M12 x 100 mm long 60 degrees.
40NM initially on all head bolts Then... 60 degrees on all Then another 60 degrees on all Then the M12x140mm bolts are a further 20 degrees

The torque specifications for the cylinder head bolts on a 1995 Suzuki King Quad 300 are typically around 15-20 ft-lbs (20-27 Nm). It's essential to follow a specific tightening sequence, usually in a crisscross pattern, to ensure even pressure. Always refer to a service manual for the most accurate and detailed information specific to your model.
Tighten them to 11 ft-lbs first, then to 22 ft-lbs, in a criss cross pattern. The 2 smaller bolts are torqued to 52 in-lb, then 104 in-lb.
Oh, dude, you're really getting into the nitty-gritty with those torque settings! So, like, for the cylinder head bolts on a Nissan Caravan diesel E25 ZD30 engine, you'll want to torque them to about 98-108 Nm in a specific sequence. Just make sure to follow the manufacturer's guidelines to avoid any engine troubles. And remember, torque specs are like rules - meant to be followed, but also kinda boring.

If your getting that far into the engine you need to at least by yourself a haynes or chiltons repair manual for the vehicle your working on because in some cases you need to replace the head bolts.

No. The bolts may line up to actually put the head on, however your horsepower is due to the matching of the piston head with the cylinder head to produce an even flame across the top of the piston. It is important that the radius on the piston matches the radius on the head. The head on the 380 will not match up to the 250 due to the larger piston volume of the 380 vs the 250 or 300.
For the 1994 Honda FourTrax 300 4x4, the valve clearance settings are typically 0.004-0.006 inches (0.10-0.15 mm) for the intake valves and 0.006-0.008 inches (0.15-0.20 mm) for the exhaust valves. The torque specifications for the cylinder head bolts are usually around 16 lb-ft (22 Nm). Always consult the specific service manual for your vehicle to ensure accuracy and proper maintenance.
