I would like to know who did the work originally. Interesting though...

We did not have time to flow an exhaust port yet, these are GM's flow numbers. The intake flow numbers when we got them were very close to these, and we assumed the exhaust would also be in line. We will get a head over and flow the exhaust ASAP.

NOTE: GM's numbers for flow tend to be very conservative.

is this with rockers?
are the 650 lift springs duals or single?

Scoggin Dickey

iTrader: (34)

These prices do not include rocker arms, pedestals, gaskets, head bolts, etc. They are just the assembled heads.

The .650" lift is a double spring.

the intake rockers are different from LS1, Exhaust is same?

Scoggin Dickey

iTrader: (34)

Correct, the intake rocker on the L92 uses an offset rocker. You can re-use your stock exhaust rocker if you would like.

Scoggin Dickey

There is no bare CNC'd head available yet. I have not heard of any plans to release them bare either.

Whats the minimum combustion chamber size i can get from these heads?

Vr6aaron

I sec that.

Scoggin Dickey

It would be the same as the regular L92 heads. We have not milled them farther than about .030" so I cannot say for sure how far you can safely mill them.

My bare castings I bought from you guys cc'd at 68.5. Factory spec is 68.4 +-1cc. I milled mine .040" and I am now at 62cc. Every head could be a bit different but this is what I came up with on mine. I milled them that far because I am building a LQ4 with the dished pistons. With a .045" gasket I will be at 10.8:1 static CR.
