Porting small block 915 j-heads

So how do we upload pictures?
Every site I go on seems to be different??
Took the pics with my phone and downloaded onto my computer and what now???

Wow I DiDiT! how did that happen, top class technophobe at work here...:mob:

340 J floor waterway.jpg

340 J cutaway with template.jpg

The floor of the J port is about 1" from the machined face in stock casting (approx).
This J port head cutaway from Weslake Eng. is approx 7/8" to the highest point above the waterway.
I have another single complete Weslake 'ported' head that I tried to copy in the past but went through in several places trying to do it exactly the same.
I suppose a rust free unused 50 year old head doesn't have 50 years of corrosion waiting to 'bust through' like all my other heads lol...
