ok so there my set up....

b18a1 block
ls crank
ls rods
pr-3 pistons
sleeve guard
*all parts new*

i have a full b16 head with dual valve springs and mild port polish.. i want to upgrade my whole cyl head. wat is a good set to invest in?

 

depends on the cams too..
for most applications portflow would work great.
RM is also an excellent choice

 

i was told i should do the whole blox set up valve train and cams...bump
