Then I'd go with a performance rebuild, hypereutecti pistons, internal balance it. Stock rods with good bolts. Id use the LA-X magnums (uses std LA rockers and intakes) and a solid flat tappet around 230°@.050 and a static compression around 10:1. An RPM and Edelbrock Thunder AVS 650, small tube headers. That's what I'd do.
