They sound good. They seem to cheap to be made here.

I think Mark 69 is running them on his car.
Remember we looked em over couple years ago at Spring Fling Andy? The pretty much looked like a off-shore Edelbrock copy
I love Mopars so much I'm date coding the skid marks in my underwear.

The combustion chambers dont look very good.
If a man speaks while in his garage and his wife does not hear it, is he still wrong?

They do look an awful lot like mine. I have the CPPA heads with a full port job by Toth Performance. My Speed Pro pistons are .014" down so I had to use the Cometic .026? gaskets to get 9.5:1 compression with the same 84cc heads. I'm very happy with them but total expense with porting, gaskets, fluids and all came in just under $2500. If I had to do it again I would probably go with Trick Flow.

I have a fully ported new set that I ended up not using. I might let them go if someone wants to make me a reasonable offer.

I didn't realize those were the same, yes those looked cheap at show. Get what you pay for.
I was thinking going aluminum on Tanks next engine if I don't follow through with plan 4BT which is what I really want.

Were those the Todd Marsh Sidewinders?
When I was researching building the GTX motor, I looked at my options. I liked the Sidewinders - yes they are a knock off head but the casting looked quite a bit better than the Eldebrocks I have seen. The casting looked real good. At that time I was not aware of the TrickFlow heads. I wanted to stay with standard port heads/intake and I felt that these heads would easily make my goal of 650 hp - fully ported.
Well my goal changed to 700 hp, and it would need to be too racey of a motor to get 700 hp out of these heads so I went with the TrickFlow 270 heads with a Mopar 337 intake. That met my 700 hp goal (results were 713 hp at 6000 rpm and 707 ft/lbs torque at 4600 rpm).
The one thing with the Sidewinders is they have a large chamber. That makes it tough sometimes to match for compression. My fresh spare motor would actually work very well with these heads (about 10:1 compression) and I should probably just save them for this motor. I have no plans for the spare motor right now.
