took my block out of the wash and noticed a ding right on the top of the sleve, so i had it machined down....had to do almost 15thou to get it out (yes he did both sides the same)
just wondering if my valves will hit now? im putting it together next satureday but it would help me sleep knowing im still ok.

ive read about people taking off from the heads but never the block...how come?

 

also is there any gains in hp to expect from this?

 

Are you on KCL Forums?

In theory your compression will go up because you've decreased volume, Id measure how high your piston is going to come out of the block now, id be a bit worried about it running into the combustion chamber.

 

yes sir
ill rotade it by hand with no head gasket in and see if it clears

if it hits can i try to take off from the pistons? or just get a thicker HG?

 

At that point thicker HG is the only real option i believe.

 

Lots of people do it, its called "decking the block". I did it to my engine to optimize the quench (0.036").

What rotating assembly do you have? You'll definitely want to measure the deck height and pick your head gasket thickness accordingly.

Keep us posted.
