Best Seller Blitz Ls 250 Cylinder Heads W/ New Take Out Gm Beehive Springs (ls3 Cylinder Head) Best Choice [zoXe8wWg]

Blitz LS 250 Series (LS3/L92 Cylinder Head)

The Blitz LS 250 cylinder head is a competitive alternative to the OEM (Mexico) casted LS3 cylinder head, they come standard with magnesium valve guides installed and a 3 angle performance seat-cut. These cylinder heads are designed with an aggressive port, which offers a sharper torque curve and quicker throttle response. It's a perfect cylinder head for any one wanting a street/strip setup. The Blitz LS 250 head will also support a well-tuned naturally aspirated LS3 to 600hp.

The Blitz LS 250 are built with a thicker base casting, wich is great for power adder setups (supercharge / turbo), and CNC porting

Note: These heads can easily upgraded to heavier performance springs to allow for more cam lobe lift.
