Message: [QUOTE="golfer, post: 985389, member: 266"] if the valve stem to guide clearance is out of spec, then it'll need either oversize (stem diam) valves...or new cast guides machined/installed. not cheap. the factory 'guide' is actually just the casting itself...so there's nothing to press in/out...its full machine work to 'cut' the guide boss out... then a new guide can be pressed in and seats cut, and valves installed, lapped, etc...make sure the valve recess (depth from head to face of valve) is within spec. OTTOMH..I think it's .060"+/- Bending the pushrods like that is retarded...never...ever seen that (on an other wise stock ish hp engine). I'd suggest that you measure the piston protrusion...to see if they are 'sticking' out too far (or far side of spec). If they're poking out more than .025-.030" at TDC...I'd seriously consider addressing that. All the pistons we sell are shorter deck height, to address this issue, as well as allow for some head/block surfacing w/o increasing PTV clearance. pistons should be ok..as far as touching valves. But I'd definitely get his valve springs replaced if he's going to fart around with his EB on all the time... [/QUOTE]
