As far as I can tell from the ones I’ve had in my shop.......the Sidewinder and SM are the same head.

so the SM that that they are selling now are NOT like the victor ?? EDIT, looking on Ebay you can fin the Pro Comp Victor copies for sale. nothing like the SM or Sidewinders. the SM's I find have a heart shaped chamber

Pro Comp is Speedmaster.
They have both the Victor and RPM style heads.
The pics I posted are of the RPM style heads. These are what is being talked about as being easy to get to 300cfm. This is the head that’s the same as the Sidewinder head.
SM, Sidewinder, Stealth, ProMaxx, E Street........ those are all direct competitors.
The Victor style heads flow over 300 ootb, and frankly....... in my mind aren’t really part of the conversation when one is looking for “budget” heads.

I would have been disappointed with those results with those parts Did they tune it at all or just run it like assembled to break it in?

I looked on Speedmasters web site & all I could find was the Victor copies, Thanks for the clarification Dwayne.

Summit sells both types of both brands I'm going to advise my customer on which ones I would use but let him make the final decision I may buy a set of the M.W port side if they make them with standard rocker arm oiling instead of pushrod oiling they show for those size heads on Summit site I'll call Speed Master, Pro Comp, direct to find out

From what i'm told the Trick flows are the best out of the box. The others can be made to work well with some investment. You have to look at the price of the recommended rocker arm for the head as well. Rocker arms for the Trick flows are more affordable. If I ever did it again, I would go for the TF270. Sounds like a lot less head aches and hidden cost with that head. dont they use regular style rockers

I believe they do, that's why the rockers are more affordable. I have the victor heads which take an offset intake rocker resulting in a very expensive rocker set ($1100). but trickflows take regular ?

Small block heads here but to bad you missed Speedmasters 40% off Black Friday sale. I bought two bare heads for 219.00 each shipped to my house. Everything they handle was 40% off.

too bad speedmaster doesn't have any 210cc big block heads, they haven't for a while now. I've been checking hoping to see some sort of 30-40% off sale so I could get some bare castings... i dont know what to buy lol
