Which heads do you have? The 241 is a really nice head to work with,I "m porting mine too, not too hard.Have you ever ported any heads before?You need to get a good 6in long (flame shaped)burr.About 35 to 50 bucks, I got mine at the local speedshop.If you have an aircompressor you can use a cheap 1/4 air grinder from Home Depot or Lowes,cost about 25 bucks.You need a good light too,I bought a desk lamp with a long flexible neck and halagen bulb at Office Depot is was about 35 bucks.Hey it cost MONEY to do your own!!I"ll check back on here tonight I got to go to work.

How's it going? I am new to the site. I have been reading it for a while and just registered. I have a set of heads I am planning on porting myself. I have searched all over and have not found any real good info on porting LS1 heads. Pictures would help a lot. does anyone know of a site with the info on it? I have never ported heads before but I am pretty compotent mechanic. any help would be great. I would like to save the money and do it myself but if all else fails I'll just have them done.

The heads on my car casting # 241. I bought some off of a 2002 with a casting # of 862. Are there any differences?
Well,. I just found there is a big difference. 862 castings are from a truck and have smaller valves. what would be the best thing to do, scrap them? my goal is 400+rwhp. Kind of have a sinking feeling right now
