Subject: Re: Engine rebuild/upgrade project by flyboy on 2010/2/20 13:54:39 What kind of guides are you going with? Liners or entire replacements? When I was porting, the aluminum seemed harder, more brittle, at some of the exhaust valves. I wonder if cracking would be a concern when the old guides are driven out? Also, the guide bosses, being thinned out now are kind of delicate looking. |
