    Got the heads back from the machine shop this past Saturday. I think he did a good job. Since the main concern with porting heads is always the exhaust I went a slightly different route and had him open the sides all the way to the gasket, kept the floor the same, and opened the roof almost all the way. Now they are basically a D-shape. I think these should flow nice. No flow bench to verify but we'll see how she does on the dyno once put together.

    L32 heads: decked the surface for flatness, 3-angle valve job, tank, paint, check for cracks, replaced two valve seats (found 1 crack in between the stock intake/exhaust valve seats), gasket match port job on the intake runners, ported the exhaust. Kept the combustion chambers and bowls stock. I didn't feel the need to 1) pay someone 400-500 extra to do the work 2) too lazy to spend the 20+ hrs to do it myself. It's just the daily beater lol.

    - stock valves
    - milled for .650" clearance
    - crow cams 130lb springs
    - comp cams titanium retainers
    - comp cams valve locks
    - ported intake, exhaust, valve job
    Scribed the stock head with exhaust manifold gasket:



    After porting:

    Finished head vs. stock head











    Not as much done on the intake side as I'd like, but, its smooth all the way in, just not opened up as much as I was hoping for...
