for the price you really cant beat them. The Thumpers supposedly flow similar to the TF 170 11r heads. Thats not bad assuming you can trust flow numbers 🤣 🤣. I will probably do their early 180 with the small valves since I have stock pistons.Ive had 3 set of flo tek heads. great for the price. flo tek heads, b303, tf intake, lt headers 5 speed 310rwhp after tune.
I haven't tried the thumper one yet
Well, the phone is a poor example. The container is the root of all problems, or all solutions depending on which side you prescribe to. Malcolm McLean in 1956 brought offshore to the masses. Before, this time frame, it was not feasible. No one bats an eye at slave labor, literally. Which just reinforces that people operate in their own self interests, whether they choose to acknowledge it or not. Human hardships be damned.There's a lot of hypocrisy that goes with those preaching "Buy American" while typing on their imported phone and computer technology. The fact remains that the orient have some superior casting facilities that are sought out by American companies needing superior products. I love my country but I'm the first to admit that many of my belongings originate from other countries.
I remember businesses moving to Puerto Rico in the 70's to save a buck. It's sad but outsourcing foreign built products and labor is nothing new. I also remember what the government did to the American farmers back then.
Does anyone know where I can buy an American Mustang without parts sourced from other countries?
Back to heads... Don't rule out the Promaxx offerings. They feature quality parts and are built and machined in the US.![]()
They are new Flotek 180's from about 2019 or before. I forgot the date I bought them from Thumper, that was in the SBFtech forum. He had already gone through them, and I wanted them for a 306 planned, and asked him to replace the springs again. Way back everyone knew Thumper from working on tons of Ford E7 and GT40 heads. I trusted him to discover any problems with the heads and fix them. He said they needed some minor casting work around the valve bowls near the seats etc, but nothing serious. The ports are fully cleaned up, they look ported but as I suggested, I think he just barely touched them.
If you're selling, let me know. I can't find how to PM someone, if you know how.......PM me.They are new Flotek 180's from about 2019 or before.

Funny thread, I thought this might be about Thumper doing a set of Flotek heads, he's been gone for a long while.
I bought a set many years ago from Thumper, which he did go through, after a buyer didn't pay for them. I also have changed directions(work truck to be retired and sold soon). So I have a "new" set I'd like to sell, Thumper installed a spring kit(beehive of course) suggested by Ed for a custom cam. These were cleaned up fully, I would not call them ported, he said they were still about 180cc, and 58cc chambers.
I'd be interested in the Flotek heads, what is your asking price?Funny thread, I thought this might be about Thumper doing a set of Flotek heads, he's been gone for a long while.
