Don't have flow numbers but I have a set of each.the TF 220s are worth the extra. Can't Really appreciate the TFs over PRC until you have the two in front of you. But They have revamped their CNC program and are putting out a better head now than before
Just wish they would smooth off the edges.

no no no you do not have to run roller rockers with TFS heads...they have the same guides as any aftermarket head, afr etc...so afr's should have roller rockers too...don't believe all the hype

also the 220 as cast are about one of the best bangs for the buck right now...I believe RPM was running a special for 1680 shipped with free milling and a set of pushrods...that's a great deal...

Your going to be looking at heads & rockers to get the TFS setup running if you have a camshaft under .600" lift. If you want to run over .600" lift you'll also need a valve spring upgrade. In other words your comparing a $1500 set of heads to $2200 for heads, rockers, springs!?!?
You might consider the PRC 215 or 227 heads if your considering spending that much $$$. They will use a stock rocker system & sell fully cnc ported for the cost of a as cast head...

These aftermarket castings are the culmination of years of developement and design. We've been very pleased with them so far!
