400 Non Stroker Build

if you're planning to splash out on the stealth heads now and are considering a stroker later i'd do it the other way around. build the stroker for similar money to the heads and a basic build then if you need more later add the heads and you won't have to pull the motor to do it. fit it once and be done with that part. i'm betting the extra torque the stroker gives and you won't need (you may want but that's different) the head swap later. just my 2 cents, but i hate doing stuff twice (rebuild, then rebuild again with a stroker kit).
