Just as the title states...

I'm going to be running a 5.3L engine for now in my RX7, and I know that I would be much better off to open the stock heads up and have some larger valves installed. I can get at a set of LS6 valves for cheap and wanted to double check if the valves would clear the bores installed in my 5.3L heads? My numbers look like they will just fine, but my math on that is rough, and I'm far from trusting it in this scenario.

I did search, but there is very little info on LM7/5.3L performance stuff here or on PerformanceTrucks.net, so... anybody?

Thanks guys-
