Water Crossover / Cooling


Hey guys, I'm working on a 331 build which has a Weiand 2X4 intake, non-crossover 331 heads, and the HH timing cover / Chevy water pump. This engine will be going in a open engine bay street rod so cosmetics are kind of important. In order to solve the water crossover dilemma, I used a HH #21401 Crossover & thermostat assy. Being that these 331 heads never had provisions for a water crossover, I simply drilled and tapped the front of the heads to mount the HH crossover assy. This required the water outlets to be more toward the center of the head in order to have a flat surface for mounting. (pic available here:) https://www.facebook.com/JohnsonPerformance/photos/rpp.278887112257394/1212573295555433/?type=3&theater

My concern is that this lower mounting position may now cause an issue with a steam pocket in the upper part of the heads. I'm considering running steam lines out of the forward intake block offs, but I'd like to keep this as clean and as visually appealing as I can.
Anyone have any suggestions or insight into this situation?

Or instead of steam lines there use drain cocks like those on the bottom of the block.

My thoughts would be to have it nose up on a steep hill or ramp to help any air pockets purge.
