Thanks for the advice everyone. The engine itself is not aimed toward performance (a daily driver), I was looking for ways to prolong its life through the use of roller parts, but as a bonus roller parts tend to "free" up the engine and allow more horsepower because of the reduced amount of friction (when compared to regular rockers, full roller rockers are advertised to give anywhere from 10-35 horsepower by just installing them). As for the heads, I could've bought some regular 302 or 289 heads, but I got the 351W for the same price as the others. I was also looking at other things such as a lightweight flywheel to help reduce stress on the engine; my ultimate goal is to have an engine that will last for a long time.
