pulled the heads.. yup several valves wernt completly sealed. about 1/4 inch on the valve waasnt sealed by just enough to not work

 

OMFG wasnt expecting the call from the machine shop today saying "well we cleaned the heads and well your not gonna belive it but". yes what am i not gonna belive "They are both cracked all the way to the combustion chamber". SON OF A......... bought those heads 2 years ago so i cant even go after the person who sold them to me

 

Wow that REALLY sucks! Are they repairable or a total loss?

 

Damn man! How much are heads for those engines? And are they stock?

 

stock heads. had bought the set for 400 as a spare set. they were clean and mine were well nasty so i wanted to use them. oh well machine shop is gonna clean my old ones up

 

Great! Are your old heads ported or anything?

 

nope guese i halfto do that when i get them back here

 

so lets see.. got the heads from the machine shop and installed.. now there is no spark on any cylinder??? i have a hand held programer that i can see im getting 90-130 rpms while cranking, 5 degree of advance on my timing, and i know i my temp sensor is reading 80 degrees also. fuel injectors are all working just no spark??? im lost

 

wow wow really i hate GM... there was ONE blue ground wire by the front right side of the block not attached that stopped it from sparking.. wtf no codes ever went off

 

So you're good to go now?
