Swap heads or not???
Hey guys I have a 6.0 iron block (370 cu) all forged that has A.R.E. 853 ported heads. They flow 305@ 600 lift (2.02 and 1.6 valves). I have a MS3 cam on a stalled a4 3200 vig. I'm thinking of swapping heads maybe some AFR 225 or similar what are your thoughts? Will bigger heads give me a lot more HP over the ported 853's. The car is built for N2O spraying a 250 shot. If i go bigger will I lose any low end torque?

not necessarily the 225s would go better with a larger displacement engine ie: 408 with yours i would go with afr 205s or tfs 215s the smaller combustion chamber will give you more compression which will give you more power. but if your on a budget some good ls6s will do a nice job as well

Okay now I had one speed shop tell me get the AFR 225 over the 205's. Since I only have a 370 cu I understand what you are saying. Now I'm wondering will the 205's make more power than I'm making now with the ported 853's. I compared both flow numbers and my 853's flow 305@ 600 lift very close to the numbers of the AFR 205's
