Can I do a short block and re-use the factory bolt on parts after they've been cleaned and re conditioned? I know that is also money and time and possibly not a good return on investment. Trying to save $$ as well.

It is inevitable you will have to rebuild your current cylinder heads or purchase new cylinder heads since oil is probably making it past the valve guides. There are plenty of reputable vendors out there to help you with the cylinder heads.

excellent thank you Q. I have some calls in to some machine shops in northern and southern california. Everyone is super busy right now. I will try and get the block and heads reconditioned and stay with (mostly) OEM parts. I will be sure to take many pictures along the way so when it's done I can create a basic rebuild thread for those who want to do this on their own.

Regards,
