Hey gang,
been a while since I've been around, .. been busy working on ports
and cnc programs.
I'd like to share a few things with you, ..
I just did a total re-work on my 15* small block Chevy head, ..
new ports and chamber, .. flows in the 390 to 400cfm range depending
on valve size and application, .. makes killer power.
It uses standard 18* cast manifolds and shaft rockers.
We are using HIP processed castings for a stronger then cast cylinder head.

The real killer is the new 13* stuff, ..
We now have 5 different ports for this casting, .. and have a new version designed
for big inch small block Chevy's at 440+ CI.
It's a 320cc port that flows well over 440cfm with a 2.23" valve and can
support 1000 HP.
We use either custom built cast manifolds with custom adapters or sheetmetal intakes.
