Budget cylinder heads for a 318

on another engine, a 318 in an 83 D250, I bought my 1st set of EQs these were bought bare and I assembled them. Magnum heads with LA intake bolt pattern. Added a stock 360-2 bbl Melling cam and lifters and a standard (NOT "RPM") Performer and 625 Edelbrock carb plus a set of Hooker Super Comp long tube headers to an untouched 135k mile short block (other than the cam). The Magnum head to LA block swap, is a piece of cake. I could not BELIEVE the difference, how much that 318 woke up in that heavy 3/4 ton truck....... would have been more magnified in a much lighter A body.....
