porting and polishing
porting and polishing i bought a set of ls6 heads that i am porting and polishing my self, i am not nessicarly increaseing the ports but i am takeing out the imperfections and polishing them off, i am curious if anyone has pictures or any recomedations for porting these heads, open to any sugestions, if you can't post pics on here cause i know i have problems posting pics sometimes you can email them to me @ cheesenr7@hotmail.com Thanks
just do lots of reading and look at a lot of pictures of ported lsx heads to find out exactly what you want to do.I would practice on a cheaper 853 before i did an ls6 head,just my opinion.I was in the same place you are and had my ls6's done by very experienced porter.I have done small block heads but didnt want to chance it on the 243's.There is plenty of material out there and if your confident give it a shot.Et performance has a lot of good pics on there site.

That thread has some pretty good info in it.
Here are some pics too. The first two are 241 casting, but you get the idea. The third is 243 I believe.

If your gonna p&p yourself, leave the intake runners kinda rough. This helps with fuel atomization. You can make the exhaust runners glass smooth. I was told this by a buddy of mine. He does cylinder heads for speed inc. His name is rich groh. Good luck with your grinding.

thanks for all the input, i just finished up one cylinder head, im not doing a all out race port and polish just takeing out some of the casting marks smoothing out the area around the valve guide then polishing it off. Finished off the exhaust side w/ 150 grit and finished off the intake side @ 80 Grit. In my opioun the LS6 head is a pretty decent head to begin w/ for street/strip use
