More L92 Head Q's
 
Searched but didn't find and my head is going to explode!! I plan on bolting up to my LS2. Will they use the same rocker arm bolts and head bolts? Is it the INTAKE rocker that is offset? I found a few threads that say it is. On sdpc website the exhaust rocker is over twice the price as the intake. That dosen't make sense.

the intake bolts are the same. The intake is offset. l92 have different rockers u can get them through sdpc. Its not a bad price. But as far as rocker bolts i couldnt tell u. When u get the heads trust me u wont be dissapointed.

The Intake rocker is the offset rocker. The exhaust is common to LS2 (and LS1, LS6). You'd think the common rocker would have the lower price.... go figure GM math. :eek2: :jest:

That just doesn't make sense!! I'm not going to complain.

I just bought a couple of rockers recently, and paid less for an LS7 intake rocker than an L92 intake rocker. I haven't had time to mock up to see if the LS7 rocker will fit the L92 heads. I'll try and make some time this weekend.

Both intake rockers are offset, but the valve spacing on the L92 is spread farther apart than the LS7. I know it sounds stupid, but it's true..... about .035" farther. It might work, just not *perfect*.

So how long before Jessel, Harland Sharp, Crane, and Comp break out the 1.75, 1.8, and 1.85 roller tip rockers for the L92 heads?

Also...I believe these have a 71cc combustion chamber. Is that correct? Bolting up to my LS2, I would like to maintain the same CR or even a touch more. How much would they need to be milled to achieve 10.9 or 11:1 ratio?

About .030" to get it up around there.

Now thats digging up an old thread!

I was looking for some info and saw nobody ever really answered your question, so I figured I would.

Thank you! I am glad I went the TFS route rather than the L92.
