Default GT 40 heads on ebay

I see that there are some gt40 aluminum heads on ebay for around $550 for the pair. Has anyone had experience with these, the add says that they are cast in australia and that they are fully assembled. Not sure if they are actually a Ford product. I have a 91 lx with a 5 liter. I have a cobra intake (upper and lower) and I am currently looking for the best heads to go with that intake. The car is a weekend cruiser/summer driver. Thanks.

Honestly I have read over and over to stay way from these heads, when i was in the market earlier this year. Maybe some here has purchased them but pretty sure anyone else here will tell you the same. In this realm you absolutely get what you pay for.

What's wrong with these heads? It would probably be a good idea if you get them to go ahead and upgrade your pushrods and springs as well as invest in some ARP head bolts. There are a lot of little things people don't think about when doing H/C/I upgrades that can cause problems down the road. Honestly, if I had the money I would probably make an offer on these heads. The gt40x heads are a decent upgrade for sure. Along with intake and cam you can easily make over 300hp with them.

With the rockers, guide plates, studs, shipping and tax.... You are getting quite close to the price of AFRs or something similar.

I looked at these when I started planning my build, although I didnt have an intake, I ended up getting a Top-End kit for a reasonable price. Seemed like more of a deal and it removed the guessing part.

I don't know exactly, I just know I've read numerous times that some of the "knock off" alum heads on ebay tend to have issues...OR, as you said, the cost of upgrading a lot of the valvetrain would then lead you to the cost of comparable name brand heads.

Looking at this item further, maybe these aren't the knock offs. They don't say whether they are x heads or not so at a quick glance they look to be like these:

Great posts guys, thank you, I know there are many heads out there, but here is the loaded question: what is the best head to go with my intake? I also have 32lb injectors, long tubes, x pipe, and flowmasters.

I would be very leery of those heads.. 550$ shipped for two heads?? take into account shipping them will be roughly 50-60$ plus the materials it took to make those heads, the valves, guides and springs the cost starts adding up. You really gotta think wow they must be using some crappy materials to make any profit off these.. I would search the classifieds for a pair of twisted wedge 170's you can have those for a few more bones and they will make ALOT more power. Plus you're not running a inline 2.02 intake valve on stock pistons.. With a TW head you can. I would say hold off and wait. Like the old saying goes! "good things come to those who wait".

Oh and i almost forgot, reading down on the list of parts that you should run with those heads it lists rockers that are supposedly supposed to net you 35HP?! lol these rockers better be made out of magic or something that's a bucket of bull sh it.

230897045318 correct 1.6 stainless steel full roller rocker arms with a set of 16 poly locks (35hp gain)
Oh god.. and they are made in CHINA... you'll be finding the needle bearings in the oil pan.
