Can't afford to buy these heads but will be sending in my 241 heads to get ported and polished by you guys within next month sure I won't be disappointed

[TexasGTO]

Whelp... I'm sold. Where do I buy? Oh wait... I already bought them! lol

[Canadiancarguy]

You know a lot of people complain or are so religiously against using Texas Speed or say things like they are way overpriced ect... but at the end of the day it just look at all the R&D and testing and so on and so forth, not going to Lie I will probably give them a call at some point. I'm not rich by any means at all but one thing I do like is good quality parts.

Hi there really liked watching your video. I have an ls1 with mildly ported heads. I would like to use this car for drag racing and occasional street use. My car weighs around 1800kg with me in it 3.9 diff gears and a 3500 rpm stall backed by a 4l60e.
I am currently using a 227 - 234 @50 cam LSA is 112 . Lift is 600 intake and 600 exhaust.
Intake manifold is standard.
The car is reasonably quick on the street and has instant torque but has only managed a 12.4 on on the track.
What cam would you recommend to get the times down given what I have to work with.

On I ordered my heads a week ago and still haven’t even shipped yet. Charge went through on my card……🤔🤔🤔🤔

Here's a question. How can you physically tell the difference between the PRC 265 LS7's and the PRC 285 LS7 castings?

………… did you guys just knock off the opening doom soundtrack?

[mohgt]

how much hp can i get for ls2 engine ??

[ryanericw]

Do prc heads start off as casts, or billets? I swear mine look like billets when I ordered them in 2013

[BadAssEngineering]

I wish I had more money, I would be giving you calls left and right

[DanielOrtegoUSA]

Dang, I'm getting old. I had to wait until 2:06 on the video to find out what PRC stood for, because I struggled to find the answer on the web.

[airbornegarage]

i have a ls3 maro, what kind of heads for that one

[adrielmarte]

Would the Precision Race Components Stg. 2.5 LS6 Heads be good combination for a 4.8 vortec???

[jdsurratt]

Ordered and received my heads/cam (227/231 116LSA) package, with all the upgrades) for my TVS2300 powered Gen5 6.2 Silverado w/ TSP headers. Should have installed and dynoed next week. Anyone want to guess the numbers? Right now, with headers only @ 6psi, stock air box and stock exhaust after the high flow cat it made 501/568.

[utahcountypicazospage]

Has anyone had any problems with these heads right out of the box

[mrmeadowsiscool]

Yeah heard the castings suck ass too. Heard the rocker stands break on the ls7 heads
