Im running a 244/248 .612/.615 113lsa in my 408 with Patriot stage 3 LS6 heads. Their dual springs are good to .650. No problems here. Specs on the heads are: Stage III LS6 heads, 62cc combustion chambers, 2.08 intake & 1.60 exhaust valves, Patriot gold dual springs. Dont have any #s yet. But I will real soon.

If you are going to save your money for better heads then i would do it right the first time and save for the afr 225 or a set of the ET performance heads. <-------- I think thats what they're called. If you go w/ one of these i dont think you will have any regrets.

I had mine ported locally. They are 225cc and flow right good 
Don't have any dyno or track numbers yet - too busy tuning customers cars to get to my own. But I hope to get it done soon!

I have out of the box AFR 225's milled to 69cc on my 408 with a 253/257 643 646 112lsa cam w/ manley nextek springs. I choose to keep the AFR's untouched due to the fact i have not seen any #'s to suggest that porting them more really helps
