Possible blown HG, head shave required?
I suspect i have a bad HG, when I run the motor without the radiator cap , bubbles appear after it gets to temp, but only after I press the throttle.
I want to do the job myself, but want to know if I should shave the head if it hasnt overheated.
any thoughts?

you cannot tell by looking at text on a thread, nor can you accurately tell by seeing a photo, only way you can tell for sure is to give your head to a qualified machine shop to check for straightness.
A head can warp even if it is not overheated.
You also have issues of the head and/or block pitting. So sometimes like in the case of my rebuild, I had to have the block shaved because of the mostly the inability to get an actuate ridge ream after boring out the motor, and instead of doing a valve job etc etc I just went with a brand new assembled head.

When I first turn it on, the temp gauge might max out for 10 to 15 seconds and then drop to a little over 1/3
I lose alot of coolant and have not seen external leaks anywhere, it gets pushed out into the overflow tank--
I tried pulling each plug wire while it was running and the piston second to the front didnt mind that i just cut the spark, so i wonder if the leak is there...

well get a compression checker... it threads into the spark plug hole.. While you're at it. pull all the plugs and take pictures of them. How do they look? Get a coolant pressure checker. It sits in place of the radiator cap and with it you can pressure up the coolant system to see where leaks are.
