On another note let me know what you would like to see picture wise of these builds. There are a lot of pictures of the first SOHC build on our website at www.keithcraft.com if you want to check them out. We will post some more in the future. The heads do require quite a bit of work out of the box which is what has not been told. They flow about 330 to 340 on the intake and we take them up almost 400 cfm at .500 lift and 420 cfms@ .600 and this is how we make a lot of power with a .570 to .600 lift camshaft and this does not kill the valve train. Same thing with the exhaust we improve it quite a bit as well. If the engine was a full race deal where we raised the ports and used sheet metal intake and all the flow would get close to 480 cfm on the intake and we could make 1000HP normaly aspirated but not many of them needed right now at about 50,000.00.
Thanks, Keith
