Oye. i'm trying to do a do a port job on some gm441 heads, and i really need to see some pictures of good porting work. It doesnt matter if they're lt1, ls1, l98 what ever. I'm just looking for detailed shaping of the the bowls and around the valve guide. Any pic would probably help me. if you can email them mine is ingerex@charter.net Gracias.

 

Here is a link to a write up I made about two years ago. It is LT1 specific, but a lot of the information can be related to many heads.

Once the page opens, just click on DIY Head Porting: http://members.***.net/gmarengo/

That is not my website, just my write up, and photo's. nuke61 was kind enough to host it for me.

Hope that helps out a little.

Mike
