Are the Titan rockers still being made?

thank you nick. i have an older set of Titans, and they are well made, i think they use a larger diameter shaft- but not sure and they use some weird metric combo thread on the adjusters - so i ordered a couple of replacement adjusters from minispares, and will find a correct tap to clean up one that has a fretted thread ( after about 5 years of race use ) - Alas - as with lots of parts - these still required some shims to assist the alignment ( not problematic but i just wish they sold some in a kit with it.)- when you spend good money but then have to wait another week to make some shims or order some it feels a bit like getting a shiny new ball joint with no shims - just poor form. Having said all that i also have a non roller version of the Keith Dodd rockers and they do a good job too-
FOR me - Best design MED LDW type , best made probably the TITans, best bang for buck The Minispares non roller 1.5 -- but i haven't seen the calver 1.4 ratio ones - which should be an excellent fit in a fast road typr build

Over sized ball adjuster screw threads too.
I have the MED rockers, nice quality compared to some, I also have the ARP 11 stud kit as well.

50 years ago, I used to use Triumph Spitfire rockers.
I got a better rocker ratio, and they are offset, which meant that I could offset bore and tube the pushrod holes and then open the inlet ports right out until they broke into the pushrod holes, which I smoothed out with epoxy.
I see that these days they make Triumph Spitfire roller rockers.
Any idea of the ratio ?
I've heard of people also using rockers from one of the Toyota Corolla models too. I think they are 1.43:1 Ratio.
I should think that it is about 1.5.
When I realised that it was an improvement on a Mini, all that concerned me was that the valve springs didn't become coil bound, so I never measured the ratio.
I have an old Herald rocker shaft somewhere. If I can find it, I'll try to get an accurate figure.
I know that I ferreted around in several Longbridge scrap bins to find a fourth un machined pedestal, so that I could get the geometry correct.

Just a quick note about the MED roller rockers, some of them use a 4.5mm allen key for adjustment. Nothing wrong with that, just make sure you have one in your toolbox because it's not always in a typical allen key set.

I have found the Titan K nuts can destroy the threads on the 3/8th adjusters....replaced the adjusters and with alloy nuts no issues.
Keith Calvers 1.4's non rollers are a really good choice, look similar to the old S rockers too
