Response to BT HiRiser Mod.

The BT HR heads cast 3 years ago fixed that already. The water passage is still there (both ends), just a lot smaller, and has much more "meat" around the outer head bolt tube... and into the the water, as well as a "bridge" across the top to the valve cover rail, plus the rocker pad is beefier all across the head and around all head bolt holes too. I only torque the head stud nuts to 95#, haven't had any issues at over 14 to 1 and/or over 1000 HP.

I am not sure what mods or upgrades they were talking about, maybe someone will chime in on that. Art usually does something new/different, every time he casts them. Always trying to improve.
