    Experience with repro cylinderhead

    Hallo there,

    I am rebuilding my TR3As engine and found leckage in the cylinder head between the water side and the cylinder 2 exhaust channel- some crack inside the head. So probably hard or impossible to repair - No big thing, just leaking little water onto the exhaust valve an limiting the water level....

    As this head already had some cracks repaired I would prefer to discard it now.

    So apart from finding some used head and rebuild it the alternative is the cylinder head produced by Moss - Has anybody out there some experience with using this head?
    I would go for the cast iron version, not the Aluminium one and the goal is to get a reliable engine for fast motoring, not racing.

    Thanks in advance

    I bought the aluminum head when they first came out, and haven't had any issues. But I don't do a lot of miles a year.

    @ Peter:
    Thank you !

    @ Darrell:
    Why did you go for Aluminium? I would guess, that the cast iron version should be more robust, same thermal expansion and a true copy of the original.

    Hi Johannes,

    I was interested in the lighter weight, and better resistance to knock.

    I was going to comment that, if you want cast iron, the originals are available for nearly free. Then I see you are in Frankfurt...so may not be that case over there. Still, if you are interested in the iron heads, I would think you could get a good used one shipped for what a new one will run.
