[tortuga]

As ive gleaned from lots of reading and talking, these heads were bought absolutely bare and given to valley heads in Northridge CA to assemble. We went with Ti intake valves and Ti retainers, dual springs 180/360, and their marathon valve job. I am pretty confident that they are done right...

One thing that was a bit disturbing pulling the heads off the FRPP crate motor was the location dowels were seemingly not doing much, block engagement was minimal and they looked bent? Think some of my trouble was poorly aligned heads on the block...i drifted in new ones and the new heads clicked right in. The intake als seems to ride better when dry fitted...

The thing ought to be making noise by the weekend!
