x2. Those prc ls6 heads from Texas Speed are a little over $1k. But That 102 is a sexy ****. Gains should be big going from a 78mm stock intake.

Thought the TBSS intakes and the Gen IVs had the same design. Just cathedral ports instead of rectangle.

I just read what i typed and realized it didnt make much sense. Im curious to see how much the 90mm or the 102 fast lxrt gains over the stock 78mm intake on the 99-07 trucks... since they gain like 20 hp with the fast over the 90mm tbss/07+ intakes and the tbss intake is a pretty good increase over the 78mm like (15/18) or around those numbers... if that makes anymore sense... so in theory if it were a stock engine with the 78mm intake the fast lsxrt would gain like 35hp over the stocker....

charlie you got a great set of heads sitting on your motor right now, i would invest in having those heads reworked, i hear nothing but good things coming from those casting way better than any other head, take it for what its worth but i would at lease look into it. well almost better than the ls3 lmao

My bad Charlie, we were texting back and forth yesterday when you could have been playing with your new toy, haha

That's going to be a mean setup, can't wait to hear how it runs!
