leak down test/compression readings 2L

[Sportivo7@domain.elided]

hello everyone,
my 73spider is burning too much oil.i did a compression test,first readings 
were done dry,then the 2nd with a little a bit of oil in the cylinder.across 
all four cyl. i'm getting 145-150 dry,175psi wet.How does sound???

secondly,how do i perform a leak down test(suspecting valve guides) and what 
kind of readings to expect.

anyone know of were i can get a rebuilt engine (expecting the worse 
scenerio)or some headwork done in so.calif
much Thanks in advance
