Swap to LT4 springs and retainers. Cheap and easy.

"Supposedly" Crane has a spring and retainer kit good for .550 lift on
vortec heads without any machine work at all to either the pockets or guides.

Check with Patriot performance in Rainbow City, they had a smoking deal a couple years ago, they took new vortec castings, put stainless 2.02, 1.60 valves, screw in studs, 5 angle valve job, mild porting, big springs, and drill the heads to accept old style valve covers, or the centerbolt, and drill to accept old and new style intakes, i put a set on a hot rod boat engine, loved them, think they were around 650.00 cant beat that

These are hard to beat for an out of box head. ready for a .520 lift cam http://www.summitracing.com/parts/sum-151124/overview/

Finally found the cam specs! Spent around $1100 for gaskets, head bolts, reman heads plus machine work( drilled for old style intake and shaved for high compression) cam kit w lifters, oil pump, timing chain, and tune up!

I think that is one of their Extreme Energy cams. It is a great cam for a 355 with good vacuum. I wouldnt go any larger though. We are running one in a 355 with Edelbrock heads and it is pretty stout. Also tried to run one with their 12-254 grind, way too much duration for decent vacuum.
