Maiden voyage after heads and LT install

I am having problems. At low rpms I have a stumble and at WOT it pulls, but it doesnt even break the tires loose from a roll in 1st! Almost like I'm running oon 7 cylinders. Feels weaker then my previous setup. I dunno. She backfires to, loud! I adjusted the rockers on the dr's side while running but the backfires got worse (even though rockers are quiter). Maybe I got 2 wires crossed? I did new Taylor wires and NGK plugs (TR6's)

double check your wires make sure they are not burnt on a header. sounds like 7 cyl like you said definitely. also check plugs are not cracked,,, I cracked my #1 NGK think I over tightened it but it was fouled.

Maybe you cracked a spark plug Just wiggle em all with your fingers and you can rule that one out. I feel your pain though, diagnosis of the stumble is torture. Glad you finally got it together.

You'll feel stupid but it's the cheapest repair ever.
