Roughed in one of my 862s I might used on my 5.3 block going in my 84 z28. What does everyone think so far? First time doing a set of heads I have how ever done some tpi and efi ford stuff along with some m62 stuff as well. I feel pretty good about them so far.



Intake down runner





Intake from chamber side





Exhaust from chamber side





Exhaust from header flange side

 

I must add that I am on the fence about using these as flow bench numbers will make that decision for me. This is what happens when the shop gets slow lol

 

cut out the intake rocker arm boss

 

The rocker bolt bosses have been cut out. Just can't see the little hole from the angle of the pic. Was trying to get a best over all shot of the port. I didn't remove a bunch of material from the runner just a little clean up and reshape. Want to keep port velocity high. If these heads flow around high 130's at .200 and increase strong into the 290's at .500ish ill be happy and pry use them.
