OK I have done something dumb. On my 1992 F150 with a 302 I am rebuilding the engine. I have put the engine back together about 70% and then I realized that I put the heads on the wrong side of the engine. The thermactor plugs are in the back not in the front where I need them. I live in Connecticut so I still need emissions. I ordered new plugs,but can I get the old ones in the back of the heads out? I really don't want to pull everything apart.
Please help
Thanks Eric
