TOHATSU & NISSAN 60/70 BILLET HEADS

***Pre release orders, limited numbers***

We are excited to finally add to our performance product line, high compression billet heads for both the Tohatsu and Nissan 60/70HP outboards.  We worked with a proffesional two stroke engine builder to develop our heads.  FCR heads are a true center fire, full squish band billet head with interchangeable domes.  You may have heard of squish and what is it?  Our domes have been designed with the optimum squish height, squish percentage and squish angle to the piston crown.  All of which are key factors for a well performing dome.  Water cooling has been greatly improved with a even cooling pattern around the domes for a consistent burn temperature.  Unlike the original heads, each dome is perfectly CC matched for a smooth firing engine.  We didn't stop there and designed a built in dry stack fitting into the head for a dry stack exhaust.  This reduces water mixing with the exhaust gases for a cleaner less turbulent exhaust flow.  Hose and hose barb are included and drilling for the hose outlet is required.We can offer a blanking plate if the dry stack option is not preffered.  The head includes all hardware including Titanium head bolts and thick stainless steel washers. The 60/70 block could not be an oring design and utilises a factory head gasket which squish height has been calculated into this.  We offer a 32CC dome for a 'typically' ported engine producing around the 160/170 psi range.  We can offer domes for stock port engines and custom CC domes for highly modified ports upon request.  The heads use a factory thermostat and we recommend the BR8EIX spark plugs (sold sepearately).  Heads are proudly made in USA and expected to ship September 19th.
