Evening bump. You know you want these.

Rock_Daddy

iTrader: (8)

Bump for the day. I will probably list on eBay if these don't sell today.

I will try to add pictures today but you all know what they look like.
All of them on eBay at the moment seem to be buy now for from 859 to 959 so 750 should sell I'd think.


EDIT: Added pics at top

Will this work on a 383 or 402 LS shortblock, or is it too big for such?

The sticky here gives tons of info but I can tell you a 4.0 bore is needed absolute min.

These are some great heads people. I just got to look at the pair a friend of mine bought. The quality looks WAY better than my 6.0 heads.

I get dealer pricing from where I work or I'd be all over these myself. I'm sure they will sell quickly. If not, let me know the best you can do, and if I can save a buck shipped, I would just as soon get yours as another set from Watson Chevrolet.

These are assembled with GM parts? What type spring- single or double, how much lift is allowed? What type rocker/roller?

Rock_Daddy

iTrader: (8)

Its all stock. I think the springs are just like the LS2's have stock. Not sure the lift stockers are good for. There are threads describing this but the intake rockers are spcific for these heads as they are offset like ls7 heads are so you need l92 rockers for that but the exhaust are the same as all other LS stockers.

The rocker arms for ls7 or L98 is 1.8

Rock_Daddy

iTrader: (8)

Im not sure if that is a question or not but as far as I know L92 Rockers are as follows

All 1.7 raito

The intakes are specific to L92 only heads and are offset like LS7 but they are not interchangeable.

The Ex rockers are the same as any ls1 or sl2 rocker and are interchangable.

OK, guys your twisting my arm. I dont want to list these on ebay and pay fees and all that. I wanted the money this weekend so Ill make the deal sweet.

Same 750 plus shipping and I will throw in the 8 oddball L92 specific offset intake rockers for nothing. You will have to get yoru own exhaust but they are the same as the other ls stuff.
