My evo jumped time, the valves bent and cracked the valve guides. The dealership says the head has to be scrapped, does that sound right? Can they be replaced? What are my options? Has anyone had work done with MAP?

 

You can definitely replace them. The dealers don't do work like that. I would look into bronze valve guides.

 

A reputable machine shop should have no problem replacing valve guides...

 

So bronze valve guides. For valves, oem or aftermarket?....all of mine are ruined along with my lifters.

 

Aftermarket are less expensive. Get SS intake valves and Inconel exhaust valves.

 

Okay, so cams...gsc s1 or s2?

 

Depends on you. S2 will make more power but you give up some drivability as cams get bigger.

 

Are you able to elaborate on drivability?

 

How did it jump timing?

 

The compression balance belt broke and wedged between the pulley and the timing belt causing it to slip and slamming the valves into the pistons.

 

balance shaft eliminator kit while you have it all part?

 

Why take it to a dealership?? lol

Yes, valve guides can be replaced. Any decent machine shop can handle them. Go for bronze guides too.
