Default Heads for 404ls2, leanin towards milled l92

I have a 404 ls2 right now, ls1 heads, ls6 intake, torquer v3 cam.

I would like to do heads but they just seem too expensive for me. I am thinking about selling off the ls6 intake, and maybe buying a pair of l92s/l76 intake/nice tb. I believe i can afford a setup like that. CR right now is 11.5 and it runs phenomenally. Should i get the l92s milled to be about the same chamber volume so that CR stays the same?

How much power are we talking with a setup like : 404ls2, torquer v3(or similar cam), milled l92s, l76 intake?

How much power would i be leaving on the table by not going with some high end heads?

bump this guy needs help so he doesn't get beat by a H/C car lol



In all honesty I don't see any problem with switching to the L92 heads aside from the fact that they are finicky about cam choice. Milling them down sounds like a good idea to keep your current CR and they flow great out of the box. I wouldn't hesitate to do the heads and then later on down the road changing the cam if you so desire is an easy swap.

We're finishing up a 370cfm L92 cnc ported head that would work great for this application. Pricing is as always very reasonable, and you'll be able to get them milled for your desired compression free of charge!!
