PRC 220 Heads? Did TSP come out with a 220cc as cast head and just go under the radar with it? I was browsing their site last night and came across these and can't find anything about them. Has anyone heard anything about them??

They have an as cast version and CNC version, is this like an as cast 215cc head they used to offer? God I hope so.

I was actually wondering about these a well. In my last thread I was asking about ported 243s and the consensus was to go with an as cast aftermarket head (probably TFS 220s) however no one mentioned these ever, I tried to find out as much as I could about them but didn't come up with much. If anyone has any experience about them I'd like to hear it.
If you opt out of the spring kit they're only $1450.
He used the wrong link, here's the as cast version.

I was the one that recommended the trick flows in your post.
I don't know about these. All I know is I have had a phenomenal experience with the TFS 220's and they cam at a recommendation from my tuner/builder who is one of the best that's ever been. And he knew of them from using them and the results from them
But with all the R&D and testing texas speed does theres no reason to believe the 220s wont be an excellent head. I would have a hard time choosing between the two, but would lean toward the TFS only because of using them before and being so happy with them.

If you look at the mid lift flow data for both Texas speed and Trick Flow you can see why people like the trick flow heads. Having great flow at Max lift is not everything. That being said I'm sure Texas speed has made a good head, I personally went with the TFS heads because BTR had them and offered the valve/bowl blending service. So it was an easy 1 stop shop that I could bolt right on and go. I really like BTR, service is good and the are helpful. I wish I had some knowledge in regard to the Texas speed heads...… I did have Texas Speed grind my cam though and it was spot on. Cars are fun!!

Exactly. flow at max lift is almost useless as a single comparison item, well.. it doesn't tell enough of the story.
I'll dig around for the test that really shows it.. trying to remember the title of it right now
Here: http://www.superchevy.com/how-to/ght...s-head-to-head
Cathedral vs Rectangle. so that's a bit off topic but to get to the point. Cathedral head flows 338 cfm on the intake, the rectangle LS3 head flowed 372. Both are Mast heads. Both are 11 degree. Both are 70 cc chamber. Both ran on a 408. The better flowing heads made 1 more hp and 2 more ft lbs at peak numbers vs peak numbers. Both heads were ran with a FAST 102. Both had cams optimized for the heads and they ran both heads with both cams. But the rectangle port heads made considerably more torque under the curve and therefore a higher average power number, more average power makes the faster car. Also, they would be a lot more fun to drive. When they kept the cam and only swapped the heads and ran head to head with same cam they only saw a peak power diff of 5 hp if I recall correctly but considerably higher tq under the curve with the cathedral port that flowed a lot lower cfm..

I just installed a set of as cast 257cc ls3 heads and lost 3lbs boost. they are also 6 bolt heads in case i ever decide to upgrade blocks.
something to keep in mind when comparing flow sheets is texas speed flows their heads without a pipe on a 4" flow plate. I want to say trick flow and others flow on larger flow plates with 1 7/8 and 2" exhaust pipes.

I have prc 220 as cast on my '98 ls1 sbe, with a Titan 4 cam, ls6 intake, lt's, 9" Moser w/4.11s, monster stage 3, etc. It made 427/391 to the wheels on a Dynojet at Doug Rippie. I've had it to the track once, and it trapped 115.6 with a 20 mph head wind, no traction, and me fiddling with launch and shift points. It sure feels like there's lots more in it.
I dislike that TSP makes so many of their castings 6 bolts. I can't use a 6 bolt casting due to clearance reasons so I'm forced to either machine a new head, or look elsewhere.
