how much for the cam followers?

Can you get A series light weight valve retainers?

how much for the rocker spacers and adjustable timming gear.

Hi, I don

i have been looking for ages, i would like to offer $250.

If its still for sale, I would be interested in everything but the turbo.

Answers to these questions I am using a JTS prepared head, the man knows his stuff.

What springs - JTS DOUBLE VALVE SPRINGS
What installed height - 1.610"
What valves - 40MM INLET 33MM EXHAUST (DATSUN 1600) OK THESE ARE HEAVIER THAN STANDARD
Whats the valve length - CUT TO STANDARD 1200 LENGTH MINUS ROOM FOR LASH CAPS
Whats your seat pressures - 110LBS SEAT AND 290LBS @ .470 LIFT

I have pulled the engine down and there are no marks on pistons or block it is not a clearance issue. and the spring i am using are not little, I don

Still not happy with these rockers. I have been trying to find the solution so I can run these rockers.

I have had them weighed and each Rolla Rocker comes in at 16 grams heaver. I have spoken to yellow terra and he said that yes the rocker is heavier and it will cause high RPM problems.

he said not only is it heavier but most of the addition weight is on the tip of the rocker and due to its increased inertia makes the valve float problem worse.

They have suggested bigger valve springs but I am trying to decrease valve train stress not increase it.

They also said the chev LS1 rockers have the same problem and to solve this they now make a special light weight version, but there are no plans to do the same for the Datsun ones.

I am now thinking of trying to reduce the weight of the rocker by machining it down?
