I have a set of fully CNC'd heads, the heads are absolutely beautiful, ALOT of money was spend on them.. they were professionally cnc'd with a 5 axis machine, here are some specs:
Fully CNC'd heads by Advanced Airflow Engineering.
-100% CNC'd intake ports to 200cc
-100% CNC'd exhaust ports
-100% CNC'd combustion chambers. They have also been polished (milled to approx. 52-54cc) (this will yield 11.5:1 compression with a .026" head gasket)
- Manley 2.00"/1.60" Pro-Flo valves. These are stainless steel, lightweight, one-piece, undercut at the head and swirl polished.
these heads are very comparable to AIs 200cc head. there are 3 bad valve seats in them though(they started cracking and fell out) i showed a pic of one already took out. i was quoted 300 to replace all 16 valve seats, but if you only want to replace the ones that are bad, then it would be even less!!! the heads will come with the valves, but not rocker studs,springs ect. so just throw your 1.6 roller rockers on them and some springs and you will be all set after the seats are put in. These heads work VERY well.. they were on a boosted lt1 before mine with 5psi it was going mid 10s.. so they flow very well! i am willing to let them go for $450. here are some pics.. also they are located in burton MI, willing to ship on buyers expense. they also just came back from the machine shop, they were dipped cleaned ect.
