For sale 4age big port head. Fitted with over size valves 1mm on the inlet and 1.5mm on the exhaust. The head has been extensivley ported and polished, with extensive CNC work, conbustion chamber / valve seat and bowl work (evident by supplied pics)
The combustion chambers have been cc'd ,polished and valves deshrouded. The head is to be sold as a complete unit with big port cams, new valve stem seals and all valve clearances set - so its ready to bolt straight on.
All cam bucket hole have been polished to aid in smooth friction less opperation along with the cam journal clearance checked.
The head has std valve spring but they have been shimmed 1mm . This WILL NOT effect valve spring bind as the installed valve height was changed when on the CNC to allow for this modification. 8.5mm of lift is still safely attainable on this head with 1mm further lift untill full bind is reached.
I have tried to supply as many pics as possible throught out the rebuild, One for proof that the work mentioned has been carried out and two to show the quality of the work carried out. (you too often get items that claim this and that has been done only to find out they are not what they say)
Price $1000 firm.... or $900 with a good big port head as change over
Located In South Australia - Happy to post
