Jesel, it is what comes with the Tiger heads. Quality product. Mine came with 1.9 rockers. Although the trend nowadays is to go as big as you can on the cam (lobe lift), there by having to use less rocker ratio.

Already have the cam and 1.65 ratio is about all I'll need.

I've got hand me downs from other PY members. Bought a new in box Crower SS 1.6 for E heads-They had not changed it from iron heads so the valve spacing was wrong. They sent me a new set up still not the right pushrod offset for the pushrod holes but finally got it down. The SS do look better than the bulkier aluminum Crowers or the TD I picked up for HP heads. Haven't test fit it yet.

Any reason not to go with spring oilers?

Jesel is absolute high quality. We chose them because they had rapid prototype capability. Their custom shop had the ability to easily convert our unigraphics files to machine path. They were interested and engaged in our project which is super important if you ever want it to see the light of day. We ended up with a 1.85 ratio, steel exhaust rockers because of the extreme cylinder pressure in a nitro engine, aluminum intake arms to save some weight and cost. Took several prototypes to get the geometry perfect and to get 1/2" push rods to not rub the pushrod tubes, but I am very happy with them. I have used T&D also. They are high quality and actually use a larger diameter shaft than Jesel. The reason I didn't go with them was I got the feeling at the PRI show and on the phone that they didn't buy into the nitro Pontiac project. They gave me the vibe that they would "do me a favor" and take thousands of dollars from me to make the stuff. Also, being 3000 miles away was a factor. If you have a solid contact with T&D the products are top notch.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
