Jackson 0 Posted November 1, 2008 bit of a strange one i think, i blew the headgasket last month ive had the head skimmed ported and polished and had some bigger inlet valves and seats put in its all gone back together but has a missfire but im not losing any power if anything it goes a lot better than it did before, ive taken each lead off 1 by 1 and the engine note definatly changes its also got new leads the plugs arent too old and were cleaned up before they went back in...... any ideas?? cheers Quote Share this post Link to post Share on other sites
