Are you going to use LSA heads, LS3 or aftermarket? Cant wait to see the results.

I have ls3 heads, but i probably wont use them... might save those for a fbody. Love those clear led turn signals you got!!
Appreciate it man :thumbsup:

Apparently an engine builder cut apart LS3 and LSA heads to see the difference and found that the LS3 heads are made from a much softer metal and that the LSA heads have a wing thats for emissions.

that's weird... I wonder if it has something to do with cutting down heat soak / transfer for the LSA? Any other major differences? Curious...

Ninjas... where we tuning eh?

I'm either going to tune my own for a street tune, or take it to boosted performance!
