Did you make them aware you have rectangular port heads???

 

I gave them my truck specs. I didn't mention that I had square port heads, no. Other than your previous reply, I wasn't aware that's what I had.

 

Any gen iv engine 6.0 and larger have rectangular port heads....

 

Like I said I'm a noob

I wasn't at all trying to make btr sound like they don't know what they're doing...

 

No and they know full well what theyre doing but without knowing its a gen4 engine they wouldnt know that, they probably assumed it was a lq4/9 with cathedral port heads not an L76 with rectangular port....

 

Well, in my defense I did specify L76 6.0..

How hard is it to get ahold of a set of cathedral port heads without going aftermarket? Are the heads from an lq4/9 interchangeable with mine? Or is it even worth messing with?

 

Stay rectangle but go to the GMPP CNC LS3 heads from the parts counter if you want to buy heads.

 

Did you tell him its a square port head?

Edit nvm didnt go to lat page

 

I would call them back or even go through and pay the $20 for the cam worksheet and specifically tell them the heads are in fact 823 or 0821 castings.... Im guessing they will probably recommend an ls3 cam with stage 2 or maybe even 3.... I told them i wanted to see 400-450rwhp na with my setup and they recommended the stage 2 ls3 cam.... Which i have to go drive, but have a sick 6 month old that takes precedence.....

 

I wouldn't say I necessarily "want" to buy heads, but if there are decent gains to be had then I'll go for it.

No, like you saw I didn't, but again I'm not bashing btr in the slightest.

I hope the little one gets better
What exactly is that worksheet? You just enter your goals you're looking for out of your vehicle?
Thanks again for all your help
