datzenmike Posted May 28, 2009 Report Share Posted May 28, 2009 (edited) Nothing wrong with the W-58 head. It has large valves and ports identical to the U-67 except that it has round exhause outlets. It's down side are the exhaust liners, but these can be removed and the nubs in the port walls ground out as part of a P&P. I've done this so not too hard to do. 2 weeks, I am in the national guard.....I'm not gunna PORT it for that long, lol Geeeez, this thread has gone from 'head' to 'tails.

Llittle_Llama Posted May 28, 2009 Author Report Share Posted May 28, 2009 so would I be better off just porting out this one and removing the liners myself and having it machined? I just want to have a good motor that will last and I can be happy with. Quote Link to comment

Llittle_Llama Posted May 28, 2009 Author Report Share Posted May 28, 2009 those are a bitch to get out I figured as much, but once I get back I need to have it running so I can get to work, another reason I was thinking to just swap heads. Quote Link to comment
datzenmike Posted May 28, 2009 Report Share Posted May 28, 2009 I removed the valve and slit the liner down it's length in three places with a small chisel, then pried the liner into the middle of the port and crumpled it up enough to pull out. First one took like 40 min to learn how, the other three were about 10 min. The liner is held away from the port wall by small 'bumps' so it will hold the heat and get glowing hot. Once out grind them off. http://i138.photobucket.com/albums/q251/datzenmike/L%20Z%20Heads%20and%20Motors/head78L20B620W-58exhaustlinerLarge.jpg[/img]"] Quote Link to comment
Llittle_Llama Posted June 6, 2009 Author Report Share Posted June 6, 2009 I get back on friday, and I will be pulling the head ASAP! I will clean it a little and port it, then off to the machine shop to be rebuilt and decked. Is there anything I need to ask for specifically while I am there? should I go up a size or two on the valves? what do I need to say to them so they know what I need done and don't try to rip me off?
