** NEW ** Trick Flow LA cylinder heads introduced at SEMA

The sales flyer they have been handing out says minimum bore is 3.830". See it on post 79 of this thread.
These heads are not intended to outperform a W2 or W9 race head. These are clearly marketed as a strong street strip head. If they come well prepped with a good valave job out of the box, they will likely become popular.
The same flyer suggests the FelPro 1008 head gasket, because it's a good gasket. You can run a different gasket for varying thickness, but if so, best to go with something good like a Comeetic Multi Layer Steel (MLS).
