So now I've bolted on the heads and I bought the yella terra roller rocker set from intense. I installed the metal guides and the new pushrods they provided, however when I try to install the rocker arms, I can't seem to get a snug fit. That is, even when I tighten down the rocker arms to the point that I feel resistance, there is still play in the rocker arms and I can still move the pushrods up and down slightly. Now this isn't happening on all the rocker arms.. just 8/12 of them.

Here is a video of what I am observing.


The rocker arm bolts that came with the kit have an allen-wrench type screw so I can't really use a normal socket set for it.. I'm just using a 6mm hex key.

Do you guys think I should tighten it down further? Or is my pushrod too short (not sure how that could be)?

Are your lifters still dry?

Did you give them the 24 hour oil bath as recommended?

I soaked them in oil for about 4 hours prior to installing them

Have you contacted Intense with your questions?

The rocker bolts need to be torqued to the correct amount, with a torque wrench. Can't remember the amount off the top of my head. But around 24 foot pounds comes to mind.

Yeah I torqued them afterwards, still no avail. I talked to intense, they said the pushrods are short but they won't take them back since it'* been over a month since I bought them. I just borrowed a pushrod length checker and I will probably order some comp cams next week.

Wow so the mistake was their fault then? That'd be some crap

What is their advertised length vs your stock length?

So I spoke to someone from Intense over the phone this time as opposed to email exchanges. They say their yella terras have had some reports of being slightly short, especially if a stage 1 cam is being used. The stock is 6.98'' in length and the yella terras are ~7.3''. They recommended going with an LS1 pushrod set which stock are 7.4''. They offered to credit me $20 for the old yella terra pushrods, but a new set of LS1 rods would end up being close to $100, from them. I'm going to gamble on a used LS set I found on eBay, for now, but if they suck I'll only be out $30.
