TFS or Yates Heads on stock block???
 

Ok well I see the yates heads 40cc Chamber could you run that on a stock Block?? Or would I need to rebuild the block for the heads?? What kind of power and compresstion would that be?

NOW it is time for Real power STUFF I Have and will put on after I get everthing: Accel DFI:)Mac cold intake, 70MM TB, Valve covers (COOL ONES)255 Fuel pump.
Next to get: rocker arms,Cam,TFS Heads,Injectors 26,Holley intake, What might I need???

I have no idea what the p/v clearance on those heads is. Ask Kevin Price he is running them.

But I think a 3xx anything is going to be too small a motor for them unless it spins really high.

i'd have to say the yates are probably to much, the trick flows work great on a stock engine, especially with that holley intake you are going to put on.

I wouldn't even think about the Yates heads. I have a dished piston and am pushing 14.5 to one with the 40cc head. On top of that you'll be looking at about $800 for a custom set of headers. Your intake wouldn't work either.

Yates are for pretty much drag only cars, they flow like mad but, as Sky said, you really need to spin em' to get them to work.
