Kinda have the same problem hope someone can help
I’m new to the forum I have a 69 c10 with the 250 4.1 L6 we just rebuilt it and upon first start we found number 2 cylinder had a miss and virtually no compression. Took the head off found a crack. I purchased a rebuilt head from tom at 12Bolt.com upon first start we found the identical problem a miss in number 2 and virtually no compression (my guy says he got 30lbs) is this a coincidence or is there something I missed…I need help ….please any suggestions are welcomed
