Just had my head done and wanted to share. Porting was done by Bo white, this is his +1 valve race port. This is all hand port, he is very good at what he does (as you can see)

The exhaust ports were not done yet when the pic of the combustion chamber was taken. I can not wait to get this installed.

No offence but anybody can take a grinder to a head and make it look good. The real power is how it flows/tumbles.

Alot of really time consuming ported heads use cylinder head epoxy and are far from pretty. Not trying to rain on your parade, just a bit of info! Enjoy the build!

Not raining on my parade at all, Bo has been porting for a long time, and is well known for making big numbers in the raptor community, He is not just some guy with a grinder, I have no doubt that this head will scream. But thanks so much for your input.

Right on. Thats good to hear, there are tons of good engine builders that arnt well known that deserve the spotlight. Let her rip!

I have a Bo White head on my LT-R. Any body who races the SEQuad series can attest to how it gets my 225 lbs. to the first turn very fast. Bo is a wizard. Highly recommended.

Bo is also known for his work on GM LS and LT-1 V-8 heads.
