Update. Finished all the porting and drilled the intake flanges for the la pattern. Clearanced all the pushrod tunnels ad they were a best guess in the 1st place, so now nothing rubs. Also had to clearance the valve covers for the pushrods. Motor is now assembled with fresh 1121g gaskets and arp head studs. Also put an 850hp together last night. I have a 750hp, 850hp, and 830 annular carbs i will be trying out on this once its back in the truck.
