It's a new, solid casting not an OEM head with the water jacket filled. This allows for improved intake and exhaust ports.

The first head we made ran on a single turbo, big cube engine in the LLSS class. Although we never did any direct dyno comparisons between it and an OEM head, I think it was a nice improvement performance wise. The flow numbers are considerably more than OEM which allows a larger turbo to be used.

The big cube single was mine that I sold to a buddy. That's when this type head was used after he bought it. I have another friend with a twin turbo LLSS model 180. Right now he is still using the OEM head. I don't have a tractor of my own anymore. Haven't for years. Still enjoy tractor pulling and in particular the 301 engine. We struggle to keep up with the red and green tractors around here. The improved head is designed to narrow the gap and last longer than the old OEM heads which my buddy replaces every year due to cracks.

Not on this one(and yes I know what you are talking about). The manifold is there just to illustrate how a stock manifold will fit. The intake side uses the 426 intake manifold bolt pattern so a 426 intercooler will bolt right on if need be.

It's not that you aren't doing a good job of explaining it, but I still am having trouble. I when I get to the tree and click on it, all I am getting is a chance to upload more pics.

How much bigger is a 426 valve? Im running a naturally aspirated 301 at 2400 rpm in antique farmstock and looking to get more power out of it.

Matt B. The 426 intake valve diameter is 1.835". A stock 301 valve is about 1.600 if I remember right. Depending on your bore diameter you can go with a bigger valve which will yield more flow yet. The ports are big enough. Flow bench results show that an OEM head with 426 valves will flow about 160 - 170 CFM on the intakes with a normal port and polish job. This head was at 240 CFM with 426 valves. The very first head was @ 285 CFM with 2.00 inch dia. valves. I am working to improve the port more yet and the goal is to get 265- 270 with the 426 valve.

Nice looking head. Do the sleaves have to be cut for the 426 valves on this head?

The valves in this head are located in the same position as an OEM head so if you are less than 4 1/8 dia. bore you will need to notch the sleeves so the valves will have proper clearance if you are using 426 sized valves.
It is not mandatory to use 426 valves. Depending on how the head is machined, smaller valves could be used. Edited by O.P.S. Heads - 17 May 2013 at 9:21pm |

Do your heads work with a 301 twin turbo or do you require more cubes? Very nice work btw.
