ported 5.3L heads, Ferrera 2.02/1.57 valves $200 Ported 5.3L heads, milled .015" with Ferrera stainless 2.02/1.57" valves. The heads are lightly ported. No flow numbers, but the car they were on gained 3mph in the 1/4 with NO other changes except for tuning.
The only problem is that there is a very small piece of the seat on one of the intake valves that came out. The valvejob was not affected, and they came off a good running car. So, you could use them as-is and I doubt they would be a problem. However, it's never a bad idea to fix damage
$200 for everything
