What kind of roller rockers should I get for a set of G1 trickflow heads.. can I get away with roller tip? or do I need full roller? and what brand to buy... of course I called trickflow and they said "buy there roller rockers and do not use stampers of any sort.." can you guys help me out

 

Do you have centerbolt valve covers or what? If so I think the only rockers that will fit are the crane gold rockers. I've been through this painful process and lost a lot of money. Let me know what you have as far as valve covers go.

 

Trick Flow also makes narrow width rollers for centerbolt heads. That is what I got when I got my 23* heads from them.

 

I have centre-bolt heads

 

GMPP makes a set of 1.6's that will fit

 

Although Crane does make the rr's for GM that are sold for use with the LT4 hot cam kits, they ARE different from the Crane Golds in one aspect. The slots are shorter, and a combination TF G1 head and cam in the .525 range can cause contact between the end of the slot and the polylock body. Also, the polylock design has a short hex on the top for clearance with centerbolt valve covers, and this can contact the top surface of the rocker body at full open and full close of the valve.

 

I have used both Crane Gold 1.5s and currently Comp Pro-Magnum 1.6s. I used tall valve covers to prevent the clearance issues.

 

Well I just have the stock valves that came from trickflow... so crane roller rockers will work for me?

 

I am running 1.5 Crane gold rollers with my G1 heads and hot cam using the chrome GM valves covers so I would expect them to work with the stock valve covers.

 

Hey Fevre. How do you like the Hot Cam? I plan to get this to use with my 23 degree heads and 1.6 RRs. Did you update the ECM or are you running it as is? Thanks.

 

It is a great street cam with lots of mid range torq. I have the accel FI but I would expect you would need to make a prom adj if using a GM system in order to get max results. I also have the retro fit LT1 intake.
