Generation IV Internal Engine - ported ls1 head on 402

is anyone running ported factory casting on top of 402 or other strokers?
i have a set of 98/908 casting that made 398 rwhp with A4 and will be atop a 418 or 402 and im wondering how much i will be giving up in power

also using ls6 intake

lets say for example compared to a afr 225/fast combo

Works for me. TEA 5.3 stage 2 61 cc. 8.3 DCR. Probably not optimum, but great torque.

As far as the LS6 intake, mine is working great on my 402.
