Texas Speed LS3 Head Porting
Has anyone tryed the TSP LS3 Head porting and have any results/feedback? Its only $750 to send them your heads and get them cleaned, CNC ported, CNC valve job, milled and assembled with springs you provide. Really good price considering most other places want about 1300 or 1400 for the same thing.

I had my heads done by them. Port polish and milled .10 it is now 11:1 cp. my only gripe is when I received the heads back from them there was still carbon buildup left in the exhaust ports and small metal shavings in the intake ports. I cleaned the heads thoroughly myself by hand to make them look the way I expected them to show up after spending $1k.
I did call them about the issue and basically they said they are cleaned before shipment and I explained that's just not possible. Anyways after cleaning the machining and milling work looked great and I have had no issues with fit and finish. Car made 505rwhp. |

Our stage 4 cam (235/248 .649/.615 111lsa) Should be good for over 500rwhp with our heads.
Here is a cam only Engine Dyno test vs a stock ls3 cam.

Apologies .010 As for the carbon yes it was where the machining did not touch. But if they were cleaned after CNC they should have been squeaky clean. I was able to rub my finger on port and have black on it. This was 3 years ago when I sent them my heads so there is always the possibility of it being an ex employee on a Friday in the summer.
