My same WCCH 245 heads. 65cc. ARH 1 7/8 headers. Pistons are -15cc so compression ratio should be around 9.9.
Cathedral ports like camshaft. 226 seems awfully small for a 402.
This is what I would choose, 234/238 118+4
It gives you zero degrees of overlap versus -2 that the 226/246 had.
I will drive real nice-no chop, make great torque and horspeower, and carry it.
