So for Webcams, I need? Options

[6G96GT]

I'll be porting/polishing my cyl-head and sending my cams out to webcams (294 grind)...here's some quick questions...

1) With the head work (no shaving or milling, just porting and polishing (combustion chamber and exhaust side) will I need stiffer springs for the cams?
2) What do I need to do for the stock valves? Replace or re-shim? I have no clue here.

Also, I checked out Jim Snoodgrass (he used only a 294 grind webcam and kept the stock exhaust cam, if I did that too...what would be the benefit vs. both, intake and exhaust 294's?????

when he had the 294 grind, dustin loss maybe 5whp down low VS my motor when i was still na, and gained nearly 30whp and 30ftlbs at close to redline.
unless you get an agressive cam, no need for aftermarket springs.
you will need to recheck your clearances, and change out shims after you install the cams.
