MG MGA - roller rocker question

Hi Everyone
I have an 1800 3 main in my A and I saw on Ebay a set of high performance roller rockers for sale. I am having the head redone this spring and was wondering if this a worth while upgrade?

If your engine is bone stock, it may not help much, but if you have a cam andf a ported head, you may get some good performance gains.
Don't buy off Ebay - go straight to the source! Its cheaper! harlandsharp.com and click on customer service.
They will make you a custom set with any ratio you chose, or mixed ratios for intake and exhaust - for the same price!

Jeff,
what does mean cheaper? I have tried to contact them (by e-mail) few times but no answer. I am looking for 1,5:1 rollers for my B. On e-bay you can get one (used) for 250 USD, but as you say there is no warranty, and you do not know what you have bought as long as you do not install it in your car.

Got roller rockers for the 3-main 1800 in my MGA from Ted Schumacher (TSI). $250 new. They were a little tight on my rocker shaft, but a machine shop took care of that for about $20. A nice upgrade with my fast road head from Sean Brown.
Chris Sloan

Kris, I mean they are less expensive. They fit the shaft perfectly and are excellent quality. There are 5 email links on their website. I emailed them last week and had a reply the same day.

Going from a 1.426 to a 1.5 rocker for $250 is not my idea of well spent money, the difference on a street engine will be notional.

Spend the money on having the head improved as that is the bottleneck on these engines. After that a different cam.

Here's where I bought mine.
