Another LS Vtec question, but this time its legit

[StreetSweeper]

Alright i have heard many things about the lsvtec and well i haven't found an answer to my question, if built right how long will the ls vtec motor last? i have heard that if it gets built properly it will last between 20-30k miles and then you will have to get it rebuilt, is this just another myth or is this true?

If it is built right it will last alot longer than 20-30k. Key word DONE RIGHT! If it is done right. If the block and head is newer it will last longer than if you use a block that already has like 150k on it, and a head that has alot of miles as well. If it is a new block and head, then I would say you could get almost the same life as a stock motor, but probably a bit less. I know of one that has been running great for the past 2 1/2 years (roughtly 30-40k) and is still running as good as ever!

Mine has about 30k on it right now and still going strong.

How high are you guys reving the LS/VTECs that are being driven for long periods of time. Noremac: could you direct me to some info, or perhaps inform me a bit of how the GSR head on the 95 LS block works? is it the same as the ls-vtec with a b16 head?
