[67cruiser]

NOT saying im going this route but, I am running casting 13 heads on my 67 GTO, virgin heads, new valves and matching springs for my Crower 60916 cam, Comp. valve job. Seems like most Pontiac guys want around 1,000.00$ for flow work and redo my heads that flow from 220 factory to about260 cfms. I might be better off selling the 13,s and buying a set of Elderbrocks. I DOON,T want to change cam or gears in my car.Question is Elderbrock makes 2 versions with differant cc,s. witch one should i run on my 400+ .040. 373 gear car.
Is this the near best way to go???????
