More info on re-making a new batch of Weslake 8-Port Heads in links below:-
Quote:
"The combustion chambers are 25 cc with room to mill to 17cc. The exhaust port floors were raised a bit to improve flow. The head as you see it, has CNC milled runners. Every head will have the same finish. The valve pockets are all milled for maximum flow and the valve sizes remain standard 1967 1275. The heads flow more than any other head on the market and do not need big valves to make HP. One customer claimed to be making 175 HP at 7500 RPMs using modern injection. Based on testing you can spin the engine to 8500 and not make anymore power. Bolt the head on forget what you learned about the stock head and use standard profiles for something like a 8 port 1300 ford. The exhaust ports flow a bit more than they should but you can take care of that with a proper full length TriY exhaust. Unlike the standard head the valve sequence is exhaust intake exhaust intake exhaust intake exhaust intake. Pull the intake valves out of the head and you are looking down the bore. The first guy to run one of these heads took it to his head guy who was very impressed and confused when he found it had perfect swirl port properties. The head is not cheap. The cost is 3500 bucks as you see it in the photos. I do not have the money in the bank to make a run of these heads but if I see there is enough folks that want one I can borrow the money to make them.To get the cost down and not use Chinese labor, I need to make at least 25 heads. The heads will be made in the US by one of the best head makers here. I will not put my name on any head made by folks I don't know. Unless you put a twin cam head on you A series you will not find a better head. It is very close to the Westlake head with a few changes to make it better."
