The latest issue of Mustang and Fords had a good article on a company called Power Heads in Fullerton, CA. They use CNC machine and make stock heads into real performers; as much as 38 HP over stock heads. Has anybody here ever used their heads? Here's a link to the their web site. However, their site is not as good as the pictures in the article. http://www.powerheads.com. Considering you get a complete set of heads that flow and make power, they seem to be a very good bargain for the price.
sounds good for a restoration that wants a little more pep out of the stock looking engine. but for the race car you also want to lose the weight and the aluminum head cools off faster. i wouldn't have a problem with them on a mild street machine. by the time you buy a set of heads and have everything done to them you'll probably be spending about that anyway.
Those don't seem bad for the price. I have over $1000 invested into my pair of heads and they are somewhat similar to what is offered here, at least it's a good set to start working with.
Also you may want to check out Thumper heads at... http://www.thumperoforangepark.com/ Take a look at the combos and check out the shipping deals. I`ve seen alot of guys on the 5.0 Mustang message boards I visit who were VERY pleasewd with Thumpers Product.
<asbestos suit>Not worth it IMHO. Either of them. Sure, they make good power for what they are, but they will never beat a set of decent aluminum heads. Being that they cost darn near what a set of aluminum heads cost, why bother? Also, I know Thumper does killer port work, but I have heard that he just reuses the stock valvetrain parts which has led to some ppl floating/dropping valves. Buy a set of trick flows and have twice the head for just a little bit more. Make even more power if you have them ported/polished. Not to mention the weight savings.</asbestos suit> Just my $ .02
Where are you finding "complete" not "bare" aluminum heads for just a little more than $700.00? For the "pair"? Last time I did the math, the difference between $700 and $1,200 (hypothetically assuming you can buy a pair of complete aluminum heads for that) was $500 - a 71% increase. For a street machine, that's $500 that can be spent on other parts or machine shop work. I'd like a set of aluminum heads, but for the price, the Power Heads seem to be ideal for a street machine. I didn't start this thread to start a pro and con discussion of cast iron heads vs. the aluminum head. Heck, I know that stuff. I mainly wanted to know if anybody had any experience with the Power Heads.
TFS heads can be found for $999 if you wait for specials. Jdsperformance has them for less than $1100 right now. Complete brand new GT40 Aluminums can be had new for less than $850 shipped. I wasnt really arguing that aluminum heads are better. Thats a given. All I was trying to say was that for the price you pay for tapped out iron heads, you dont really get much performance IMO. Heck, GT40 irons stock will give you CLOSE to the numbers powerheads will, and can be had for $300-$400. Then again, powerheads may be perfect for some people. They are certainly one of gazillions of choices, however I have done searches on several popular mustang and hot rod sites and have found a handful of people with powerheads out of almost 150,000 members. That tells me something.
How about complete aluminum heads for $749 a pair? Diversified Products Marketing has GT40 Turbo Swirl Aluminum Y303 heads for $749 a set. They had take offs advertised for $699 in the current magazine issues but have sold out of them so they are offering new ones for $749. My May 2005 issue of 5.0 Mustang & Super Fords still has them in the add on page. http://www.buyfordracing.com/shop/product_info.php?products_id=518
Actually my ancient motor which is a 92 vintage was built with this same headwork. Triple R machine shop in Quincy IL has been doing this for years. I have been very very pleased. I keep threatening to do aluminum heads for weight savings, but something always comes up and takes my money beforehand. I think it is money well spent doing this to heads, jmho. Dan
Yep. I plan to spend major, major dollars on the engine for my all out drag car . Therefore, I need to budget for the engine to go in the '73. I'm also working on a carb and manifold improvement for the 250 ci in the '77. I have a couple of good 302's around the house; neither are roller motors. I have a set of 1 5/8 headers and a Torker II manifold. All of these were freebies. Northern Auto Parts (and maybe someone else) has a 347 stroker rotating assembly for $695. If I go with a good cam, pay for machine work, buy a good set of heads, buy a carb, and use the stuff I already have, I should be able to build a very good street engine for a very low budget. I'll even be able to get a built AOD and stall converter with the savings to go with the 9" rear and 3.89 gears (another freebie) I already have. That should make for a wicked, very streetable car.
Yep sure sounds great, how much net HP are you wanting or expecting? btw, JMO but if I were you I would just build the 302 and not spend for the 347 stroker kit, its your car not mine so it's up to you.
There is no replacement for displacement. A 347 is the closest thing thing to a 351 that I know of and not near the hassle and trouble to put in a Maverick. Let's just say that I want the most power that I can get for the least amount of money (ain't we all). I would like to get at least 400 HP at the flywheel or flexplate as the case may be.
