IMO, there's no point in sleeper mods.
The goal to keeping the value of a low mile, low production car is not to look stock, it's too be stock. E7 heads are worth nothing. Ported E7s, lower the value of a stock low mile motor, and the heads are still worth...nothing (302 motors are worth nearly nothing now, but maybe someday a numbers matching low mile 302 in a flawless car will be worthy of auction or museum) hell, at that point you might as well stroke it. Modding the car at all, reguardless of if it's visually noticable, defeats the whole purpose of keeping the car virgin. Just my .02
Just something to think about.
