Intake Port Tumble

What sucks about this whole deal is that these heads started out as a run of the mill valve job, nothing fancy. I told the guys to do whatever they needed to put the heads in good shape. They did the guides and seats, but left a ridge in the pockets when they cut the old seats out. Looked like hell, so I requested a pocket cut. Partially my mistake, I should have just hand blended and went on with my rat mashin'.

For whatever reason,{I suspect general stupidity} they cut the 60 deg angle off the seats, leaving only the 45, and the top 30. I specifically requested a cut to the ID of the seats. Their cutting out the bottom 60 removed a huge amount of metal, requiring copious amounts of grinding to blend in. I was pissed, but decided to blend the pockets and go with it. My 1.88's now look nearly like 2.02 pockets, and the two angle valve job....well.

I'm putting them on a 360 slated for my 4x4, with a .470ish roller designed for computer compatiblity and torque. I had other plans for this motor originally, which included aftermarket heads, but my 4x4's motor has developed a rattley wrist pin after 10 years. Anyway, this tail chasing has the run of the mill valve job turning into ported heads.

Since I'm having to do a bunch of cleanup on the pockets to cope with the machine shop's screw up, I've decided to enhance the VE as much as possible given my meager skills. I didn't need the huge pocket cuts, nor do I need a large port volume since my goal is moderate RPM torque. This motor might see 5000 rpm on occasion, but not often. My goal with the port windows is simply high velocity and smooth flow, and a mild cleanup of the walls with minimal removal. I'm afraid the pockets are to large now anyway, and I don't want to do any more harm.

I don't have any pics of the finished pockets, but you can see the mount of metal removed from the cut on the chamber marked #8.
