If your lift is with stock rockers (1.7) then you will only add .05 more lift with 1.75. .613/.617
I would get rid of stock rockers no matter what. You will have to clearance the valve covers and check geometry.

actually it is .613/.616 (not that it makes a dif.)

But I wouldn't do that IMO. If you are desperate to change the rockers the try HS 1.7's or wait a little while and Nasty Performance will have a C-clip upgrade kit for stockers pretty soon

Pro magnums have been used in some very high zoot setups with excellent success.

I'll be using the same TSP 231/237 with the comp 1.75s. I'm waiting on AFRs with Patriot doubles that should have been sent last week. I'm hoping to have eveything together and dyno tuned within two weeks.
