FS: AFR 230 heads (1630), ECS Big blower cam + other valve train
Well I've come to the conclusion that I need to have more cylinder head and step up to a 6-bolt setup from my initial results. I'm only at 63k blower RPM and need to get it up to around 74-75k RPM in the sweet spot for the YSi.
I bought the H/C setup from forum member here you may know Digivex (402/Novi 2500) awhile back.
I had to have some work done to the heads prior to putting them on my engine. Nothing out of the ordinary after being run on an engine for a few years.
Work done is as follows:
Glass bead
Vacuum test
CC chamber (71cc)
Competition valve job
Resurface heads
Set spring height
Set stem height
Install helicoils (needed on 6 of the rocker stands)
Wash/assemble
*One other foot note is they have been drilled for 1/2" head studs so there are some shims you need to run on standard studs/bolts. This was already done when I bought them and is no big deal.
New PAC 1236x springs
New PAC racing steel valve locks
New Valve stem seals
While these heads are an older version of the 230's (not V2 version) they work and work well as you'll see below in both NA and boosted form.

In N/A form with a blower cam, 10:1 CR, Hi-Ram it made the following results:
93 octane
E85
Blower results:
AFR 230 assembled heads only - $old
BTR upgraded trunion rockers & LPE (Lingenfelter) billet rocker stands - Sale pending payment
ECS Blower cam - Sale Pending
That being said, the engine is still at the builder and this stuff will not come off/out right away but will be promptly removed once I have verified availability of the new cylinder heads. Or if this add goes more than a couple weeks it shouldn't be a problem then as the new heads should be available.
