LT4 HEADS

Screw in rocker studs, lightweight valves, cool, red powder coated intake... The valve springs are capable of up to .525 lift.

D port exhausts weren't a perfect match for my antique Hooker Super Competition headers but good enough to seal up with no leaks. .

2 inch intake valves and lots of sharp areas to grind down in a future porting job. Lots of potential hot spots here!

Even the LT4 manifold still has the small 52mm throttle body openings. Future planned upgrades include a 58mm throttle body so I'll have to open the intake up a little bit to realize the full benefit.
