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?????

Alright, that's not too bad (5whp) in the lower end and I like the 30 whp gain in top end.

Do you think it would be better if I were to put my stock manifold back on in place of my current header if I ported and polished the stock manifold?

Everyone I keep talking to about the header vs stock mani say the stock mani provides more torque than the header. With the cams installed, would the header be better or my stock manifold (ported and polished)?

Thanks for the reply!
