to answer your question.. yes, you need to replace them with 918s or better for a aftermarket cam.

See I figured with such an improvement on the heads that perhaps the valve springs were more durable (similar or better than LS6 springs).

Hey richard I meant to call you very sorry I had to use a set of the L92 heads for another customers car and then we were not able to get our hands on another set. I think I am able to get a set and as soon as I do I will send them your way so we can get something started. Very sorry for the delay but you know how things go sometimes. I will be in contact with you soon promise.

No worries Taylor. I've got a pair on the way. I'll let you know when they show up. No need to send out any of your cores at this time. Hope all's well with you guys.

Richard,
how long to you have your cores? And about how long after that for a CNC?
Just wondering roundabout. Also what does something like that usually cost?

Could you PM me a price for hand porting of these heads? I dont want to wait for the CNC im thinking
Thanks

Richard,
Are you guys using the GM valves or have you found an aftermarket intake and ex. valve that will work?
Manley has a custom valve that will work but kinda pricey.

I just got off the phone with Manley and they said they won't have any valves ready for at least 6-8 weeks. It looks like a standard length 1.60" stainless valve will work for the exhaust. The intake valves will have a long wait though.

Taylor, good to talk to you today. Those builds you were talking about should have some impressive numbers. I will let you know what route I end up going.

I wonder how long it would take for Manley to make some of the custom 11270-8 valves.
I called SI and they said the same 6-8 weeks before they have anything ready.

Thought this might be a good place to post, but I have a set of completely assembled L92's with rocker arms. I maybe upgrading to LS7 heads, so I maybe selling this set. I just want to get back what I paid for them, and it was 835 shipped. Let me know!

I got my bare L92 heads in today.
I had a set of dual .650 lift springs from TSP laying around and guess what, they fit perfectly. Same installed height and everything.
The ex. rocker takes the standard LS1 rocker but the intake takes the offset one. The rocker stand is different though so I couldn't bolt everything up.
The intake bolt holes look to be the same pattern as LS1 too.
I'm thinking about porting a fast intake to fit. The upper area would port out okay (I think) but the bottom would have a rather large mis-match. I don't think it would affect flow that much since it is on the lower floor.

I was this posted earlier but didn't see a reply. Will the LS1/2 headers bolt up to the L92/LS7 heads?

Yes they will, I measured mine last night and put a set of LS2/LS1 header gaskets on it to make sure and it is an exact match.
Not sure on LS7 though.

Has anyone ordered and gotten one of the car intakes from GMpartsdirect?
I'm about to give up on this L92 project and stick with my Darts.

I have been trying to get a release date from GMPP but no luck yet. I have been promised one to play with in a week or so.

They tell me that they are working on the details and should have the info soon.

Sorry about the delay.
