BT HiRiser Mod.

If new hi-riser heads become available, I suggest that the rear water passage be not drilled. This should help in stopping the cracking which has occurred. This would mean there would be a right and a left head. There is a stress riser right at the rear head bolt. We have shut the water passage off by welding. We hope this will eliminate the cracking which has occurred.
