Engine: 164 2978cc: - Looking for a new cylinder head

Sep 19th, 2006, 15:37

I have a Volvo Cross Country but not one of the new fangled thingies but a 1975 6x6 ex military truck! It has the same B30 engine as the 160 series but with a very low compression engine.

I have converted it to LPG but I need now to convert the head to run on unleaded and want to increase the compression as well. Rather than start from scratch, I'm looking for a spare cylinder head from teh passenger car as a start.

Has anyone got one in exchange for petrol tokens?

I'm sure I have a carb 164 head about.
If you want to convert the head for running on LPg then you need to change the valve quides for silicone alu bronze alloy or phosfer bronze should just be ok. I have never seen these heads suffer from valve seat recession on LPG (we have converted loads) but if you want to play safe then fit hardened seats to the exhaust valves only.

How much? I can arrange collection. It would give me a point of reference for comparison on my c303/TGB cylinder heads.
