Anyone running them? They have been out for a little while now. I know Gomer has had great luck with them, wondering if anyone else has also? Thanks!

 

They have not been available yet, so not any number out there as far as I know, except from Gomer. As I understand it they should be out soon, maybe in a week or so. I expect they will do real well. Maybe Texas Speed will tell us more on this…? We would like to know too.

 

Those are the heads that I'm gonna run. Ended up buying TSPs 233/239 cam and Jason suggested his PRCs or a set of MTI's heads. They have put some time into em.

 

The stage 2.5's have been available from TSP since 12/8. https://ls1tech.com/forums/sponsor-sales-specials/247520-precision-race-components-stage-2-5-5-3l-head-specials.html
I just ordered some last week

 

Devil Dog, I'm getting ready to call and order that cam (233/239) Monday. It should be a monster with the PRC heads.

 

Do you have them yet? We ordered some a while back for a customer of ours, but had to cancel the order because the customer needed them before Christmas. Not TSP fault, they just hadn't gotten them in yet.

 

I was told by TSP that they have sent out several sets already and mine will be shipped when they get their next batch this tuesday or wednesday. That's all I know. It has taken them a while to get them out.

 

would like to see the prices of a basic head/cam/mail order tune package i saw on there and some dyno #'s with prc heads nad a tq'er cam or 233/239 cam... that would be really helpful!

 

Once they get some out, would like to see how they do! We are putting on a set of their AFRs 205 on a car with the MS3 cam. He has Hooker LT and TSP x pipe with true duals. Will have dyno & track numbers in a couple of weeks. Would love to see the PRCs do as well with same type of set up!

 

Thanks for the info. I was under the impression they were already out for a while since Gomer has had them on his car for a while. Did you all get quoted some flow numbers before you ordered?

 

I'm pretty sure gomer's were prototypes and I think his flowed @ 317 cfm at .600 on the intake. TSP hasn't quoted me anything on the flow for the production heads, I've just been waiting so long for these to come out I figured what the hell. Good price too.

 

I have two sets on order for local customers. I was told by TSP and Racetech that the heads would be shipping in volume by the middle of this coming week. Btw, I sold my protoype set of PRC heads to a local guy here and he has made damn good power with them too. I'm going to do some fine tuning on his car in the next week or so and post up his final results with the PRC's and a MS3.

 

Sorry it's taken so long to get them right everyone! It was VERY important to me that I offered a quality cylinder head that would make good HP & we wouldn't have to worry about failures. We have some of the best ls1 components & companies in the U.S. helping us to create these cylinder heads

 

No problem here! We trust what you guys are doing and glad you are looking out for your customers!

 

Sounds good to me.

 

Thanks Jason! Hopefully we will see some results w/ these heads and the 233/239 cam since it will clear the 2.04 valves!

 

my set has been on order for a while now but i decided to wait i believe they will be a great head for the mone.Im suppose to get mine first of next week
