Pin L92 heads for use with nitrous I really want to use L92 heads on my new 408 I am building but have seen people say that with nitrous I may have issues because of the think deck on the L92 heads, is it possible to pin the heads or "dowel" them to keep them down and prevent this from happening? Anybody seen this or heard of this? Thanks in advance.

Yeah I guess that is a possiblity too, however I never hear anybody talk about doing this on LSX applications. I remember from my fox body 5.0 days that o ringing the heads and block were pretty popular but I don't know that I have ever seen anybody do that with an LSX platform, is there a reason for this?

Most of the problems I have heard of with L92 heads lifting, has been with boost, Not nitrous. Just use some heads studs and have at it. I wouldn't think spraying a 300 shot would cause these heads to lift in the least. People on the internet like to reiterate all this crap they hear about thin decks and whatever else, But they have no experience with any of it.

Yeah I kind of feel the same way but I had a reputable engine builder tell me this also and I would like to believe him because he builds tons of fast LSX motors all the time but at the same time its still a business and companies have to make their money so a part of me thinks he is just telling me this so I will buy the TFS or AFR heads from him. What to do what to do.

with nitrous you see a huge pressure spike at the hit-much higher than a boosted engine.The pressure is not as long as the boosted engine but does alot of damage in that short spike.
FYI-i don't reccommend parts to make money-it's to put out a trouble free product.I could be like some vendors who will sell you whatever you want,but i try to steer people to what they NEED.

Thats cool thanks for the info shawn, I was not trying to call you out and say you are not trustworthy or anything, but at the same time I have learned the consumer has to cover his *** too because there are some companies out there that would say things to make a buck. I am just trying to get some opionions from mulitple people and engine builders to see what they think on the issue. I have tried searching the forums for it and have not seen a lot of discussion about it so trying to get as much info as I can about it. Not trying to discredit you or VA speed. No hard feelings man. Well since you posted in the thread what about running a set of ported stage 3 LS6 heads, do you think they would flow enough air to support a 408?

If you want the square port design cylinder head and are worried about the thin deck height of the L92/LS3 with nitrous, consider the LSA heads from the supercharged Caddy's. Same port design as the L92/LS3, but they're manufactured with a denser material which is supposed to add a considerable amount of strength to the head/deck.
Just giving you another option to look at.

That is some very good info Mike and I was not aware of that. Are the LSA heads by chance as cheap as the L92 heads or are they more expensive? My whole reasoning really for wanting the L92 heads is because they are a good head and not $2500 like the TFS and AFR heads.
