The heads are ready for the 4.8 flat top pistoned 5.3 that is going into the ’87 Chevy Truck. These 862 cast heads have been fully home ported and used 2″ LS1 intake valves installed.

These heads were not flow tested, but I expect them to flow a little better then LS6 243 cast heads as my past heads have done.

I made the decision to run the 2″ valve because it was used so often in other LS motors and even in the HO5.3 with 243 heads, which is basically what I’m coping here.

I measured the throat and all diameters of the 5.3 valve seat vs the ones in a pair of LS1 heads. They came out to appear to be the same valve seat.

Springs are PAC 1218 .600″ Lift. Link below:

UPDATE:
The heads were later pulled off of the truck and milled .045″ to achieve 11.4:1 Compression Ratio.

Here is how I used my spiral tempered screw extractor to remove a very stubborn brass fitting that snapped off in the oil sending unit receptacle. Please take great caution to not rush these jobs as they can make more problems happen very quickly if you break the extractor.
