I'll either do that or double up on gaskets to get it to seal. I think the flange on the header portion of the DP was slightly warped because IIRC it wouldn't sit flat on a table, it would wobble some... It's sealed everywhere except for at the top of the flange, that's where the leak is at. The angled spark plug non-fouler works realy well. I got the check engine code at first because the leak was pretty bad starting off and the o2 bung is RIGHT THERE by the leak, so it was seeing a lot of oxygen. Now that the leak is sealed up mostly it's off.
How hard is the rocker install compared to headers? Should be easier, no? I've already bought new plastic coolant elbows in anticipation of the current ones breaking, anything else I should get?
