crow cams rockers

Gday just wondering if anyone has used the crow cams 'next gen' roller rockers
Like these.
I had no idea crow cams even made rockers until I saw them in the repco catalouge on special (for about 300 for a v8 set).
Has anyone used them and are they ok?
I know crow cams is a reputable brand when it comes to other valve train components.
Do they require head machining? Can you get an adjustable set?
Thanks in advance

M20 or M22 for 6cylinder ute?

G'day all, can someone please tell me what would be the preferred 4 speed gearbox (M20 or M22) for an HZ tonner with a 186. It's my son's first car and we've converted it from an automatic to a manual ok, but the gearbox he's used has a few noisy bearing issues and needs to be replaced. It has a 10 bolt Salisbury diff and it needs some revs get going due to whatever the gearing is I'm thinking.
Thanks in advance


Hi there can anyone tell me if I can replace my 3 speed manual
box with a 4 speed and keep my column shift on my HZ ute.
Has anyone even done this??
As a matter of useless information my first car Renault 16TS had
a 4speed column gear change.
Just thought its cool to keep my column gear change.
Thanks for any help. Tony

Some photos of my 'new' HZ

Some photos of my 'new' HZ

Hi guys, here are some photos of the 1978 HZ Kingswood that I got on Saturday morning. Its a fairly stock 202, 3 speed manual. 2nd owner car with 202,000kms only alterations that i can see are advance extractors and an exhaust that I have to say gives it a really nice note but not too loud. LPG but that was installed in 1990 and runs on both petrol and gas, and the mag wheels but they are still 14's and it also came with the original rims and hubcaps if I want to put them back on.
