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.

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. |
