Ok building a simple street motor. 455 BUDGET build re-ring, new dish forge pistons, turn crank, old 041 cam FTH, old everything I can.
The HEADS.... old #62 mild porting they have good guides (were knurled at some point) so I need new valves....
Are the Ferrea 5000 series valve good enough for a simple street engine or should I add $150 and step up?
The ONLY reason I am building an ENTIRE engine is due to losing a valve...KILLED EVERYTHING. (build date 1995.....maybe 5000 miles since)

I have been out of the hot rod scene for 20 yrs. (Being a dad 3x does that)
So the Manley's go for $350, or the Ferrea 6000 for about the same???
NOTE: i do need the 5.2 length to accommodate the old set-up valve springs install height of 1.800 .
