Well I eventually got the engine out and brought it to a Buddy's house were we tried with his proper welder.
Only got one bolt out so 3 still there.
I bought drill bits and helicoil set and when I get a chance we gonna attempt drilling the bolts out.
I've bought brand new headers,collector box,fork tubes,fork seals,dust seals and bushings. Also front and back pads and chain and sprockets.
So have a lot of new parts waiting to be put in!!!
