Im assembling a 400 small block chevy that will see action in a street driven 4000+ pound chevrolet pickup.

The short block is already finished, the cam is a a comp 270H (.470 lift and 224 duration intake and exhaust) and compression with a 65cc cylinder head will be 10.4:1 on paper, not actually measured out because I do not have the heads.

I called AFR and asked for their reccomendation. I was considering the 210cc Race Ready cylinder heads. They are not perfect for my setup but I wanted to buy something I can use down the road in a higher horsepower application. AFR reccomended their 180cc street head. The 195cc street head would also work I was told, but the 180cc would be ideal.

Is a 210cc head that mis-matched for my application? Has anyone run an set of AFR heads and been pleased/displeased with the results?
