tried to remove the head fron the block but the bolts will not give. i even tried a breaker bar....no go! what else can i do? air tools? i don't want to break the bolts or else i would be screwed!

 

Don't use air tools. You need to extended the breaker bar with a pipe. Use a smooth motion to rotate the bar. Make sure you loosen the bolts in the specific pattern shown in the Helm's manual in two steps. Otherwise, you'll warp the head.

 

you should replace the bolts everytime you remove the head.
