Re: L29 454 Build for '63 K15 with NV4500
With option 1, if it is in the budget, I would look into upgrading the cam.
With option 2, Before changing heads, I would check into what the flow/performance differences may be. I am not familiar with the 148 castings, so I have no clue if they would be much of an improvement over the L29 heads.
