Champion GN1 heads on TA block

[BEATAV8]

Anybody here running GN1 aluminum heads on a TA block?

Did you end up drilling the cylinder heads for any of the available extra coolant holes which the block provides?

None needed!

The TA heads have an index where to drill to matchup with coolant supply from the TA block.

I have a template for the head gaskets which also must be drilled, but the question is do the Champion heads have a coolant passage to match the block passage?

As was said "none needed", but a few years ago Kenny D. checked before and after drilling the water passage on TA blocks/heads, and there was a significant drop in temp around the combustion chamber.

All the high HP with crazy boost on TA block/heads builds , were done this mod, street builds not necessarily!
