So, what's it going to be this winter, slicks & a new set of rear gears, or cylinder heads :D Best play it safe, all of the above!!!

Just gears and slicks. Maybe some more boost, see if I can lift the heads off the deck.

Now call me a naysayer, but I am curious about these heads. I am a Chrysler freak so don't be beating up my tree.
What is the deal with the spark plug hole? It looks to be in at an angle, but they way it enters the combuston chamber it is right on the "heart" shape. If the plug is completely in the hole, then wouldn't it make for a shitty flame travel, if it is at the end of the hole, the steel threads would be exposed, causing possible detonation.
Just an observation, I am going back to the site, maybe I am selling my INDY heads.
