New block

[Andy Bennett]

Thanks again.
for the chest cover I did take a look following the earlier comment. I also checked using the usual books as it looked to me like the later chest cover would fit as the threads are in the middle, and it seems that I have the slightly later of these blocks with the screw in core plugs but with the later chest cover, so shouldn't be a problem manifold wise.
Also appreciate the other bits and bobs, lots to think about but forewarned is definitely forearmed and I want to make sure I don't ignore anything whilst I have the luxury of time to get it right.
