im looking to start a new turbo build on my nova.i currently have a set of l92's on my lq4 and i love them. i waslooking to stay with them but i know the lsa would be a stronger head to go with. im just curious how many people are using lsa heads, ported or unported, and what kind of power people are making with them. it seems like buying a set of ported lsa's is getting close to the price of some aftermarket cathedrals. would appreciate some feedback on combinations/power people have and recommendations.
thanks

Currious about LSA heads on a forced induction also.

same debate I am having. I was thinking of using tfs 235's but have heard good things about the lsa's also.

Here is flow data i found on stock heads. Seems to me that using a ls3 intake w a 90mm tb along w lsa heads should make respectable power. But how would this compare t a 317 headed ls6 intake setup on comparable boost?

Stock LSA heads, stock LS3 intake here and I am positive I am making around 1100rwhp or more. I like this setup a lot

There are plenty of people using the LSA head, do a search here they will pop up. I had Richard at WCCH run his program on mine and open them up for the 1/2" studs as for cost yes I could have bought a set of aftermarket heads for what I have in them but, I feel as though they are just as strong as aftermarket heads. I would venture to say 80% of the issues you hear about lifting a head is in the tune/cylinder pressure not the heads being weak.
