you can leave the intake manifold in the car, just undo it from the head and you should have enough room to lift the head out still. if you are really worried about fuel, remove the fuel pump relay, (2nd one in under the coolant reservoir IIRC) and start the car until it stalls.

yeah i might leave it on the and just unbolt it from the head, yeah its to late to start the car ive got abit pulled apart now, im just going off the gregorys workshop book i think it is, so you it should be right without doing that to the fuel system?
thanks |

if you unbolt the manifold off the head, you wont need to touch the fuel lines.

As far as I know you can still do whatever you want, but im not sure what it would run like without a tune.

You can still do the same amount of porting etc for gas. If anything it will benefit the gas combustion more than petrol. BUT if you have an venturi style mixer, your power gains on petrol and gas will be less than they would be on straight petrol.
I wouldn' worry about it to much. I got a CMS stage 3 head, 2A Cam, High comp motor, and ran it on dual fuel for ages. I didn't even notice a difference when I removed the gas mixer in the end. But I didn't drive the car back to back, it was a couple of weekend apart. But it was no big shock, indicating gas mixer won't be holding you back too much. The gas system actually coped better with the setup than the petrol system did. |

Thanks |

When removing the head, be very careful not to snap the upper chain guide off.....it's on the right of picture ( head is removed ) right next to the cam sprocket.

Is that the one that a bolt holds it on the front of the head if that's it I left in still bolted on, went to undo it felt abit dodgy so just left it. Do you know much about changing vernier cam sprocket I think it's called that. I thought I had it at TDC but looking it up on here I dont think I have. I got cuclinder 1 and 6 nearly at the top but the notch on the cam sprocket is at about 1 o clock, but my balancer mark is in the centre. Does that mean my balancer is out? |

Possibly......the timing mark on the original cam sprocket (when #1 is at TDC ) should be approx. 3mm ABOVE the cylinder head where the rocker cover bolts on to. As for that bolt, it will be very tight due to it being covered in the sealant from factory. Have you used a zip-tie to hold the cam sprocket in place ??? Have you removed the cam chain tensioner assembly ???
