aluminum lids

Yea so then as it flows into the engine it would take the heat from the aluminum lid with it and hurt performance.
and as far as heat soak goes i havent seen any dyno sheets to prove how much hp you are really loosing
i tend to think that with the amount of air flowing through the manifold you are raising the temp by only miniscule degree amounts and inversly effecting hp by miniscule amounts
IM OFFICALLY CALLING BS ON HEAT SOAK ROBBING ANY SIGNIFICANT POWER
