Roller rockers

[3100gagt]

Any body hear anything about Manta sport roller tip rockers.
I was going to put them in when i do the lower intake gasket but are they worth the $200 for my 3400?
Thanks

I would do stiffer springs aswell, get rid of the dredded valve float at 5200rpms. On stock heads the stock rocker do fine, if you are going to do heads and stuff later its not a bad idea.

Yeah I agree no real point to doing the rockers, and springs if your not gonna fully port those heads too....
Curious... what ratio were you thinking of getting??
Stocks are 1.6, and I was thinking of getting 1.7's but I dont know about the valve to piston clearance...

You know where we can find these 1.7s? I don't know of anyone that makes them for us. The roller rockers we can get are stock ratio :(

Yea I thought we could only get the Harland stock ratio rockers? (besides Mantapart) I have heard nothing but bad things about Mantapart especially for us V6ers
