Should i resleve this motor. My setup so far is endyns 12.5 pistons, using the egale rods. Iam also going to be using the b16 head with the itr vavletrain and thats it pretty much. Will a blockgaurd be fine for this setup or will slevving the motor need to be done. THe b18b block iam using for all this has only 40k miles on it. The cylinder walls are in pretty good shape. I would really like to get this build done soon. And money isnt really all there to resleve the block. But should i go ahead and invest into this or will i be fine with just using a block guard? Also I was told i need have my head ported? Iam not sure what that is yet? <_< Iam sorta new to builing or putting toghter motors. THis is only my second one but first bseries build. I had a sohc na setup. D16Z6 with oversized dx pistons.
