well see heres the thing. i know that in this application it might not be needed. but when I have quite a bit of experience seeing older B series engines picking up 10-15ish whp by doing the tricks that we do to our heads in a 'stock' sense I am simply saying that is the allowable modifications we can legally perform.

because even if stuff only produces small amounts of gains we do it because every little bit counts. this aint street racing where anything goes.
