Aluminum Heads?

I was at a gathering of funky car owners (and their funky old cars!) when I came across dis guy with a Mini and it had
View attachment 31752

an aluminum head from Pierce Manifolds. He really liked it. He said it ran cool and improved the low-end torque.

Since I'm going to be pulling my Sprite's engine apart to see if I can figure out why it's pumping air into the cooling system (ugh) and I might find cracks in the wrong places, this thing's on my radar.

---> The question: Does anyone else have any first-hand experience with these heads and if so, how well do they work? Do they hold their fluids nicely and separately? How do they affect performance? Which gaskets work, or not? Etc. I poked around with the search function and couldn't find much first-hand, real world info.

Thanks!
John T.

7 enterprised just installed one on a car in their shop. They polished the aluminum, and it looked like a chrome head. they said they don't sell many of them but usually the aluminum heads increase performance due to better flow being designed into them. I have one on my TR3A and it has more power than my last TR3A. Not enough miles to say it will last as long.

Mini Mania has sold hundreds and hundreds of them and can say without a doubt they are exceptional. Most of the 1380cc engines we build will include them as one of the most cost effective way to improve performance. I have personally have run it on one of my race cars and a street 1275 with great success. They use a stock gasket and can be fitted with the 1.4" intake valves and 1.2" exhaust valves with ease. (The stock Sprite head uses 1.3" intake and 1.15" exhaust valves). They will for sure cool better and also look great!
