hm I'm slightly confuse as to which head to use on my motor now, its got a stage 5 cam, 4age pistons, not sure which types, shaved block, quad throttle bodies, bottom end all balanced, it used to be ke25 racers 5k, and he used a 3k head on it, to get a comp ratio of 14.5:1, when i got it it came with a 5k head, i want to build it to the same specs but now i have been offered a bigport head as well as a 3k head and unsure which to use, both will be shaved and ported aswell
ok i just took a look at the head difference topic and found out that it is not actually a 5k head i have but a mildport k head :)
