A 48 degree W9 on a 59 degree block is a mess. Guys need to understand it is not the lifter angle that causes the problems with the ports. It is the lifter spacing which is 1.625" on 48 degree stuff and and 1.875" on a 59. When you use a 59 degree block you put the pushrod into the bottom of the intake runner. You clearance for the pushrod and you ruin much of the benefit of running the heads. Considering the expense of getting a set of 48 degree W9's complete ready to race you are peeing in your cornflakes doing this on a 59 degree block.

Can't understand what the big deal is with getting a good block. I'm giving away a complete shortblock in the for sale section.
