New 21 stud heads

[JK1934]

I have finally new castings for the 21 stud heads, we have the patterns & the process worked out, it has been around 4 years & a few foundry's, I finally have a good foundry doing some very good work, the castings are very nice & they machine up great, they are cast in top grade automotive alloy & are heat treated to T6, I have 5 pair ready that are pretty much all sold now but I will have a steady supply from now on, I can machine them for dome pistons to order at no extra cost, they are cast here in Australia & I hand machine them myself, I have just setup a website mercury8restorations.com.au you can contact me there & I have a FB page too Mercury 8 restorations, I can ship anywhere, thanks John
