Heads are supposed to be good

They are great for up to 400 hp but have limits. there really efficiant and make lots of power with low lifts and work flow best with flat or dished pistons in stock form..comp make a tool to machine the valve seat to fit regular springs and presto a good street head. most real high power stuff ive seen has been with roller tappet setups in the 270 @50 duration rangs lift doesnt need to be high to make power.
