Head modification

[Malcolm Parker]

The best thing to do would be to get a Ricardo aluminium head from Dave Dye.  It will fit straight on, will not strain the head studs and has an integral water outlet, so less joints in the plumbing system.  I have used planed low compression heads but they all tend to be different and the shape of the combustion chamber varies accordingly, some are thin castings and can break through during the machining.   I don't know about you but I would rather not have the grief!
