I have a ls head that's been milled .03" (just to clean it up) and was thinking about putting the head with Crower 404 cams on a stock LS block. I was wondering if there is going to be clearance problems. I have a spare block that I'm going to put in Wiseco pistons, but I wanted to experiment with nitrous on the stock block before putting in the built block. Share your experience.

Are the valve reliefs on the stock pistons deep enough to prevent piston-valve contact?

 

.030 is more than just cleaning up. When you resurface a head its more like .003 to .005. As far as the piston to valve clearance, if the head is milled .030 you should definitly clay test the motor. Having an LS head makes that job even easier.

 

specie,

I live in palm harbor & have a b18b head f/s :-)

95 b18b Cylinder Head (Stamped 94 like all 95 b18b heads)

$80 for the cylinder head with:
Valvetrain, Cams, Cam Pulleys, Valve Cover, intake manifold, JDM b18b cams out of my old 98 b18b into this head.

 

i have imed you my #
The head has never been milled :-)

 

i had 403s with about .3 milled head and it was ok but between 403 and 404 there is a good amount of difference i would def do it just to be on the safe side.

 

hey what up do u still have that b18b head, if so let me know because i will buy it!!!!!!!!
