I'm building a .060 over 350 forged crank, h beam rods, forged pistons, ZZ-9 cam, retro fitted to a roller set up. Planning on using an ACCEL, or TPIs base and runners, and 52mm TB. Should yeild about 10.5 10.6 to one compression with 74 cc heads. I was wondering which to go for. I don't want to loose any low end torque by goning too big on the intake runner size. But I don't want to choke the motor. My guess is 190's but I'd like to get some opinions..
Thanks

The only difference between 190 and 195 is that the 195 have a taller port on them.

The 190 will work the best with your TPI intake but you have to look ahead. Are you always going to keep the TPI? That is the mistake I made. I ended up switching later on to a different intake and now Im wishing that I had a taller port head.


If you are satisfied with the TPI then get the 190's.
