Deck height and shims etc

Just "had" to measure all the deck heights and head volumes for all cylinders. All the head volumes were somewhere between 68 and 69 cc (68.5 on average). I used two head gaskets to measure the deck height + a feeler gauge. The deck height was then 3 mm minus the feeler gauge. Since the piston protrudes, this measure becomes negative.

On cylinders 1 and 2 the deck height, dh, became -2.75 mm and -2.65 mm on cylinders 3 and 4. By using two 0.06 inch shims I will get a CR of:

CR, cylinders 1-2 : 7.78:1
CR, cylinders 3-4 : 7.72:1

The shims coming with the kit are 0.04, 0.06 and 0.09. This will give 0.04, 0.06, 0.08, 0.09, 0.10, 0.12, 0.13 and so on. But, it does not give 0.11. With one 0.04 and one 0.06 I will get:

CR, cylinders 1-2 : 8.07:1
CR, cylinders 3-4 : 8.01:1

This is above 8:1, so I ordered some shims from CB Performance (0.01 and 0.02 just in case). A 0.09 and a 0.02 gives 0.11, and this will be a CR of:

CR, cylinders 1-2 : 7.92:1
CR, cylinders 3-4 : 7.86:1

The I (re) checked the rings, on both ends of the cylinders this time as shown in the new Aerovee DVD.

Heads

The "sticky" feel of the engine when left for 30 min is normal according to Sonex, so I just leave it as it is with this Würth gasket compound and all.

The cylinders look nice and black (or nicer and blacker at least).

Took out all the valves from the heads and put them in marked boxes. The heads needs to be cleaned and trimmed. Trimmed the intakes to make a somewhat less obstructive flow path. Rounded the edges mostly.
