O-Ring Block Questions

Hello all. I have a few questions about O-Ring Block modifications

1) Is there a DIY somewhere that can be used as a guide for doing this job?

2) Is the block and head reusable again if the head has to come back off? Let me elaborate. If I decided to take the head off for upgrades later on down the road, is there any reason that the head would not be reusable? What about the block?

3) Where can I rent this tool from, and buy the o-ring itself?

4) Do you use a stock head gasket with this?

Thanks in advance guys

So, instead of blowing your gasket out.
it's going to blow pistons + probably ur block as well

I own the Isky tool and have done several. It's not overly difficult, just have to pay attention and take your time. If you pull the head, you will just want to replace the wire. Typically the wire is .040" and you put a .030" groove in the block for .010" protrusion.
