Max Heads

They promise to increase power output by almost 25 per cent, thanks to the inlet and outlet ports being cut to obtain maximum flow, and the huge 44mm inlet and 37.5mm exhaust valves. The cylinder heads are pretty much standard in design, apart from the fact that they fit dual valve springs and larger cylinders. The holes for the spark plugs have a diameter of M12, so these are the plugs for the smaller model. This is so the valves can be opened up without making the walls too thin. The combustion chambers come with a standard capacity of 54.50cc. BBT sells these cylinder heads empty so that the customer can decide which parts he or she wishes to use – hence the very good price! Each head is sold individually and stock is already available. WHO: BBT HOW MUCH: £249,50 CONTACT: +32 (0)3 633 2222 WEB: www.bbt4vw.com
