If anyone's interested and has a file sharing service to help upload the cad's?

The site wont let me link the files.

Hi guys, I struggled to find what I was after so I downloaded draft sight and drew up my own. I'm not sure if I designed them right or whether my drafting technique was correct but the end result is a manifold flange for the 4A bigport and 3VZ that is a perfect fit (for the heads I have at my disposal) and leaves plenty of space as well as good surface area; the 3VZ flange is very tight but fits well the 4A is a neat tidy fit.

I've also added a "63mm" three bolt flange that's been oversized to 64mm to be an external fit on 16G exhaust pipe (helps ****ty welders like myself get a sure seal)

Photos and cads for those who can't be arse drawing or spending hours fiddling to get it right.

4A

3VZ

Having trouble uploading the cads but I'll get them up asap.

Disclaimer, I can't stress enough: these drawings are designed around the heads I have available and at the hands of a layman with no prior CAD experience, and as such I will not guarantee they will work for you 100%, my advice is to print them off, cut them out and ensure they fit before committing to the laser cutter.
