L92 head question...need opinions
L92 head question...need opinions hello,
i am in the middle of collecting parts for a L92 418 stroker engine an have ran into a possible problem. i already had one head that came with my motor, and other was damaged from dropped intake valve. anyway i ordered a new head and the casting number is difference and the ports are too. here is what i measured for ports
ex. length 1.586 ex. length 1.558
ex. height 1.401 ex. height 1.310
in. length 1.234 in. length 1.253
in height 2.555 in. height 2.566
i know its not a lot but is visably different. is this going to be a concern or can i get away with running it the way they are? i cannot return the head because it was a special order and valve seals, ss valves and dual patriot springs are already installed.
opinions would be great. thanks in advance

I would make it a point to get another 823 casting if you can find one.
I have said for 2 years now, the 823 casting is better because the exhaust ports are noticeably bigger. Glad someone came on here and validated it.
Tell me did you notice a difference in the finish inside the ports as well?
