Question concerning sealing of cooling chambers, had a set of MAD EFI 3L Billet heads on my 01 300x, they leaked allot since it was only a silicone seal......how are yours sealed ?, O Ring by chance ?

Thanks, great looking heads by the way.

Mine (pictured) is top hat...like the stock 70 head but with a smaller dome. I like having a squish band personally. Top quality stuff...

The sst-60 head's have a outer water jacket cover or a 1 pc. type ?

[topgun marine]

sst60 are a 1pc head.

These where the first set of pockets (3L) in my cnc lathe
