[QUOTE="Sixfoh, post: 1545416, member: 32072"] Just to give some feedback here about some vendors. DDPM was very helpful in my build. He is sooo knowledgeable! Even knows tidbits like how the international piston are 5 thou shorter than stock ford pistons. I trusted him with his stage 2 rebuild kit, got the rcd cam upgrade and it runs amazing. A lot of the parts in the kit are Mahle which is the OEM for ford. Even take a look at your pistons when you take them out, it will be molded on the underside. Anyways when it comes to KDD I have to say the customer service is amazing. They really go out of their way to make sure youre satisfied. Which brings me to sending them my custom 100# valve springs. Which were "progressively" wound. The tighter end always goes facing down for many reasons. A couple being weight in motion as well as harmonics. Regardless when i got my new KDD heads they were installed 19 of 32 upside down. Aaannnddd 1 of the springs was their 70lb spring. Looked visually different and measured it in my valve spring compressor. That kinda ticked me off they missed one and had to go digging around their shop to find my custom spring. This set my build back a whole extra week. Thank god for my white paint dot(to mark its direction) which made it easier to find in their shop. Now i wanna mention they made good on this. With different options to revise the issues. So im certainly not badmouthing KDD as they have excellent products and am very satisfied with their heads. But note Jared the owner is obviously not building these things. He has many people working for him, like any good expanding shop! So i just want to clear the air and say they are both amazing companies. Some will have good with one and bad with another. But i do not believe either are bad. No one can expect a company to have a 100% sparkly clean reputation. Do your due diligence, trust your gut and all will work out. Have fun with the build and feel free to reach out. Just did a complete 6.4 build. Full engine, bigger injectors, dual fuelers, fass low pressure fuel, bigger manifolds and uppipes etc, bigger turbos etc. [/QUOTE]
