Is it Cheaper to get "Ford" or "International" parts

[82racin]

Just wondering is it cheaper to buy ford name replacement parts from tousley or get International name replacement parts from somewhere. (Need to know where the best place that would be) I have the international numbers for pretty much all the parts i need... Im replacing cracked heads on a early 03 6.0

Heres whats in my shopping cart at tousley ford

3C3Z 6A642 AA Oil Cooler Kit (Entire Assembly with Cover)
3C3Z 6584 AA Valve Cover Gaskets qty 2

You'll just have to price them. Sometimes Ford is much cheaper than IH sometimes it's the other way around. Turbo oil pipes are one example.

Alright. I just wanted to make sure before I put my order in. Sounds like ill just go ahead and go through ford. Not sure it'll be worth all the extra work searchin for everything just to save a couple bucks

Yea, it really just depends what exactly you are buying. There is not a good answer for you here. May want to examine options on both.

it depends completely on what you are buying. tousley works good because it's a one stop shop.

One thing you want to get through international is the ICP connector. Don't get one from ford
