I'm not sure if heads are worth it on a LT 6.2, they flow 330 cfm stock and from what i've seen so far there isn't a lot of power found there, not as much as you'd see on a LS head. Here it looks like it was worth 2 tenths maybe 3.

12.4 is really impressive from a big *** N/A truck, and it was doing that on stock heads.. Damn.

Do you have any videos of this thing? And is it a crew cab? Also, it's a 8 speed right?

so the heads to be honest i’m not too sure what the wcch are flowing at. We’ve been running west coast heads alot recently. Theyve been doing the job. Didnt have a chance to dyno the vehcile so dont actually know what power sifference was made but yeah. Its a 4 door, videos i’m not too sure how to upload on here. I’ll try to upload it. & no it’s a 6 speed. Was a 5.3 at first but decided to do the motor swap. I’m just now realizing i put 2016, its 2015.

this was actually my second set of west coast cylinder heads on LT. I use them more on LS. The gains are great! Price wise youre looking at about 2400 or so. Depending on the level porting job and milling etc.

Thanks for the feedback man, and glad you said it's a 6 speed cause I've been really considering 6.2 swapping my 5.3 truck and it's a 6 speed. The 8 speeds help em go faster so I assumed you were 8 speed being that you're running low 12's. That just makes it that much more impressive though.

The 6.2 trucks run off on the 5.3 trucks pretty bad, there's a video on youtube of a tuned intake and exhaust with headers 5.3 regular cab truck getting stomped by a intake and tune 6.2 crew cab. My buddy has a yukon denali 6.2 and it pulled me pretty good too. The 6.2 makes a big difference.

I'm not knocking the WCCH heads by any means, they have always been phenomenal heads, I just wonder if the gains are worth the money in this situation or better spent somewhere else, but I haven't seen exactly what guys are getting from ported heads on the 6.2. I've seen some dyno results where the 5.3 heads were ported and the gains were around 20 hp, and the 5.3 heads only flow 280 cfm when stock. So if they only do 280 and get ported and only gain around 20, I would imagine the better flowing 6.2 heads don't gain a whole lot either.. and looking at the LT heads they have a good straight shot to the valve so I don't think there is as much to improve on like there was with LS. But it does happen and I'm not expert so I could easily be wrong.

As far as loading videos, I upload mine to youtube then copy the link over to here. For me that's the easiest.

yeah i shouldve dynoed the heads before and after but as far as LS Heads go, the most i’ve gained from west coast on a 6.2 was 32 HP!
This is the link, just uploaded it.

Hell yeah that mother rolls out.

32 hp for 2400 ish dollars. Ouch. But it's the go fast game and that's how it is sometimes.

Monstro1326

Yeah man it's a fast heavy four door lol. and as far as the heads price goes that's what they retail. I get a bit better price lol.

I know when fasterproms boosted his wife’s Escalade it made 475 rehouse with custom boost cam for a LT4, his ported heads and E85. Then made 645 or something with the LT4 bolted on. All through the 8 speed.
