its suprising how much material i did remove judging by wat was left on the desk.lol

The ridge between the port opening and the valve has been smoothed-turning a kink into a smooth semi circle to improve gas flow. Step three: once the majority of the crap was removed from the exhaust ports i just started honing them out with the pannel flap wheel.moving in and out radiusing the port.removing obsticles in the way. Step two: hard to remove deposits were removed with a dremel and a pannel flap.also 80 gritt paper proved pretty useful on the end of the finger. Step one: basic degrease of the head.valves removed, cleaned using 'gunk' Heres what ive done so far.ive picked up another head too which im going to measure the caspacity of the ports and use latex to check port shape.will do a write up soon Ive been reading the book on engine blueprinting and alsoo cylinder head porting principles so inspired me to do my own.its not really ported out i was just looking to improve the efficiency of the ports not sure wether ive said it already but it was saying that turbo cars respond better to smaller faster velocity ports so i didnt want to remove too much material.

but make everything matched and you should see some decent gains. No ive just honed it, your not ment to polish it past were the injectors shoot into the head as the rough surface is meant to incourage turbulance which inturn mixes the fuel with air.so im told.ĭid you port match the intake and exhaust manifolds, and knife edge the ports there is a whole list of shit you can do.
