that sounds like a good setup, both sets of heads will do you justice. you'll make good power with that setup!!

The TFS heads are a little thicker and require different length pushrods, 7.50 I think, but better look into that some more. Not sure if the AFR heads are similar or not since they also have a thicker deck. I would get better valve springs with that cam for insurance purposes. I like the Trick Flow CNC 215 better than the 220 as cast heads. The Texas Speed PRC 215 heads are good too. You gonna run custom headers?

ya custom headers as well and for sure new springs. i was also looking into the cnc heads but overall im thinking afr heads
