1.7 type IV head
Hi everyone, I am getting to a point where I can get the second spark plug hole installed. I un-did some of my last porting, due to having seen someone else porting which I felt was much better. These heads are from a 411, they were from the 1.7 engine. I think the exhaust is 39mm X 41 or 40mm. Have a look and make suggestion on any imporvements I can make before the plug addtion and coating and "O" grooves.
This is the flange, the exhuast pipe will be welded to it I will need to have the seats re-ground. Hi, am havig my machinst mill me a "O" ring groove into the head and cylinders, man I need to get this engine running. Last edited by effvee; August 28th 2011 at 17:17. |

Dual spark plugs
Hi everyone, I had European Motorworks add a second spark plug to my 1.7 and 2.0 heads.
Here are the 2.0 heads. Jorge at EMW said that the second spark plug should be angled toward the exhaust valve, also there are 10mm. I will have the heads cryoed and re-coated. |
