roller rocker?

[boostedblkbeast]

I am going to be running a postons gn110t cam 212/206 in my mostly street driven T-Type. I am just looking for some advice about what ratio roller rockers to go with. I was thinking of going with 1.6 or 1.65, but are there any reasons to stick with 1.55 or to go up to the 1.65. I am just trying to get the most out of my combo. I have seen some other bio's of our cars running 1.65 rockers, but because this is going to be mostly street driven, I was not to sure if this was going to stress out the valvetrain too much. thanks

A higher ratio rocker adds lift. If you have enough valvespring clearance and it will not add too much spring pressure. (usually not a problem but should be checked) There is no downside
