I currently looking to buy LQ9 408 stroker, I dont have BIG budget for the build. I have PRC 2.5 5.3L heads and a ls6 intake from my last 346. It is better to keep the PRC heads on the 408 and buy a ported FAST 90/90 combo or buy L92 heads with a L76 intake. I dont know if the PRC heads will choke the 408 a lot. The 2 build will have a new stroker cam. I want the better the combo for more effeciency.

Thanks !

You will make more power with L92 heads vs the ported 5.3 heads. Don't limit yourself to a L76 intake though. There are better choices these days.

I know the Fast 102 is out, but I'm looking for the L76 because L92/L76 combo are in the same price range of a Ported Fast 90/90 combo. So, it's better to go with de L92/L76 with my 408 for almost the same price..?

You will get more power with the L92's because they have quite a bit of flow. For a 408 they are not a bad choice at all. The intakes do hold them back a little but FAST is in the process of finishing an intake for those heads.

alot of guys also do a victor jr. for the L92's but it takes a little bit of work and a different cam to make it work its best.
