noob bashing, lol. Just in case the author of this initial post wasn't aware VTEC is the name of the variable valve timing that makes the LSVTEC so enchanting. VTECH is a phone. But to answer your question, LS rods are inherently weaker than VTEC rods which could lead to your only problem. Keep the rev limit around 8,000 and your compression ratio shouldn't come into play that much as long as you're running 93octane everytime all the time. Do not get cheap on the gas with a high cr. Otherwise the compression shouldn't make much of a difference as long as you did the rest of the conversion right, just don't try to spin it too high.
