Just when you seem to get everything working...

Everything started clicking for me this year. Won some races. Got the car into the 9.30's. Decided I needed a little more power to complete in 9.50 class during summer months. Was going to send the heads and intake out for hand porting.
Got the heads off yesterday and found this.
3 different gen 3 hemi experts say they've never seen them crack there...
my luck continues...

Can that be repaired? I assume that the hardened seat is fine.

At least you found that before you had them ported. A friend with a set of Stage V Hemi heads had his CnCed. 30 passes later, they were junk.

When you run a cast iron 426 Hemi head on nitro that's the first place it cracks.
