I think it was locked because the mod wanted you to search.
Just from observation over the years, there is a casting boss in the top of the intake ports on LSx heads. The boss is for the rocker stands on the other side of the head. You can port that boss flush with the rest of the walls and it's the "main gain" on the intake side.
I downloaded like 20 pages once- pictures of finished ports and chambers. If you're expert enough that you want to smooth out chambers start with the 5.3 liter heads (smaller stock chamber) so when you remove material you will end up with a similar size chamber to a 5.7 head. Because the 5.3 heads have smaller valves, if you port those it will make a valve job manditory.

It was removed for the same reason your signature was just removed. You choose not to read stickies.

You're trying to tell me that discussions about porting cylinder heads isn't advanced? Ok then. That makes no sense to me, because I don't know many average joes who port their own heads or have access to a flow bench to gauge results. I read the sticky, thanks. Still don't see how me asking about methods for porting a set of cylinder heads falls under "basic" mods.
The Advanced forum is intended for discussions more along the lines of new theories of port design and fluid dynamics theory, rather than rehashing existing porting techniques. On many sites, you're absolutely correct - discussing head porting is definitely an advanced topic. On LS1Tech however, we push the envelope and basic head porting is almost routine. You should get good response to your thread where it is though, since LS1/6 internal engine is the single busiest forum on the site.

Ok, that makes a little more sense to me, but I haven't been here long so I didn't know that porting was almost routine here... and I figured most people just buy fully ported heads anyway. Unfortunately, I am on a very tight budget and I have to do my own porting and I don't want to screw anything up.

The not reading the sticky's is really getting old. A guy just asked "How do I go fast" and right above this thread is the "So you want to go fast sticky" I'm not one for posting "read the sticky's" but something needs to be done about this IMHO. I still always refer to the sticky's before starting a new thread yet it seems like very few people do. They don't even bother to read the first page of the section to see if their question was asked before. Guess that's why we have 3 oil threads on page one of the maintanence section. Very frustrating.
Anyone also noticing that folks seem to be getting more rude? I mean ok I can live with "that sucks" or "that looks like ***" but how about "Ground effects are for *******" does that not cross the line?
There was also a thread 3 weeks ago where some guy was saying he was going to start polishing parts for people and would folks be interested and another user posted "good luck I'll have that market all sewn up" and I posted my opinion on this users comment as he was not a sponsor and the whole thread went poof. I know you guys lock a lot of threads for multiple reasons but this one just disappeared. It was on the morning on May 6th. Any idea why? Just curious.

*puts on tinfoil cap, waiting for black helo's....* Mike02Z- I agree with some of what you said. You're dead on about some of it.
However, your comments about the "good luck I'll have that market all sewn up" (which I said) was taken out of context and *I* find your comments rude inferring that I did something out of bounds. I had a long coversation with that person via pm, you have no idea. Also, you were so misguided that you made a whole thread asking about it? No wonder it went *poof* No need to clutter the site with flame threads based on your obvious misconception of the matter. And if you were so pissed why didn't you Pm me?
Oh yeah... NB4TL.
