A tip to make you engine assembling easier:

When checking valve to pistons clearance and pushrod length, put a light checking spring in place of your regular heavy spring. This will allow you to check pushrod length without collapsing the lifter. Also at full valve lift you will be able to push down on the spring with your hand and feel and measure when the valve comes in contact with the piston. Minimun clearance is .075 piston to valve. Dont forget to do this with the head gasket in place and torqued to spec.

A Note From the Man...
"What can I say about head and intake porting? You are always learning. When you think you know it all you make yourself an idiot. One thing I know is I love it.
Loving head and intake work is what separates me from others; it is fun for me. This is to change the way people think about OEM Ford and other cast iron heads. What my goal is to have people say, 'I can't believe that made that power with the original heads!'"

...I have spent serious time and a lot of late nights porting, flowing, ruining ports by going to the limit, cutting apart ports, and learning...always. I can port most Ford heads to send the high dollar aluminum head whimpering back to the shelf. Let's face it, the aluminum after market heads will never be beat with the same porting as a cast iron, but the cast iron is a ton cheaper, and can beat a mildly ported aluminum head. In the case of a 460, an equally performing cast iron head costs half as much as an equally performing aluminum head."

Now I have learned that valve size is important. I have learned that bigger is not better. A little bigger may be okay, but stock sizes are hard to beat. You will see most of my heads run stock valves and maintain good flow numbers. A stock port with 2.08 valves cannot efficiently run a 2.25 valve. For starters, there isn't enough head material there to open the throat effectively. Next thing is that the efficiency drops with a bigger valve. If you take a port flowing 300 with 2.08 valves it will crush the efficiency of a 300 C.F.M. port with a 2.25 valve. I learned this from a top head man that works pro-stock. Also the air loses it's velocity when it spreads to far at the intake valve and just falls in the port instead of shooting in there. An efficient set of heads with small valves flowing equal to big valved heads will make up to 10 % more power. Amazing! Efficiency and velocity are two majorly overlooked issues."

Slow = Boring
Another huge power loss is reverse flow. This is something Nascar has worked on in recent years. I have also. This is where the intake charge is sucked back up the intake again, and where the exhaust is sucked out of the header back into the cylinder and sometimes all the way to the intake. It is very important to keep the exhaust going out, and intake charge coming into the cylinder. I have tested this until my eyes were almost popping out of my head and have found with valve angles, leaving some areas rough, not porting at all some area, and some specific notching that this can significantly be reduced. This is another way Barnett High Performance heads are different than they appear at a glance. Another way that my heads dog aluminum heads that are box stock."

Don't get me wrong, the aluminum heads for all out racing (money is no object) can't be beat buy s set of OEM irons. But for street use and low and midrange power our ported irons are enough to put a smile on anyones face. For over 6500rpms and all out racing an aluminum head is the way to go, but again not in box stock form. They have to be worked on to out horse the tricked irons. For low budget engines ported OEM cast are your most bang for the buck."
