- Measure the thickness of your head gasket and bore - When you have all the figures, use this formula for the calculation of your engine's compression ratio: CR = (cylinder volume + clearance volume + piston volume + gasket volume + chamber volume) / (clearance volume + piston volume + gasket volume + chamber volume) Now place the cylinder head on and tighten the nuts for that cylinder. If your engine is a 2.0 Liter 911, there is a gasket between the cylinder and head. This gasket must be in place to make your measurement. After you tighten the head nuts, turn the crankshaft until you feel the solder crush. The solder should crush without much effort.
An ideal spare or upgrade part for Version 3 gearbox AEG weapons. The cylinder head is double sealed with two O-Rings that expand when the piston moves to improve air seal. The head has a lovely anodized finish and comes in an attractive colour. The end of the head is dampened to further reduce gearbox noise when turning over. Features:

Unfortunately the cylinder head gaskets were not tight and blowby occured under higher engine loads - a clear indication of insufficient holding down force. The above mentioned tightening torque of 55 ft lbs probably refers to the thread of the stud inside the casings but not to the nut clamping down the head. -

Milling your cylinder head is a cheap way to raise compression, much cheaper than swapping out pistons. But then why not do this? The main reason is that when you mill the head, you are putting slack in your timing belt because essentially the head is getting "shorter". Needless to say this is a bad thing. -

To make a 225 cid six cylinder with a 3 1/8" stroke would take something near a 3.9" bore, certainly not do-able on the 170 block. Lengthening the stroke is a good way to save money and have two different displacements, and aside from a gain in low end torque, that's the only good thing about it.
To remove the valves from a cylinder head a 'valve spring compressor' is used to compress the valve springs by exerting force on the spring retainer which allows the collets to be removed, when the compressor is removed, the retainer, spring and valve can then be removed from the cylinder head.
