Port and polish 823? Alright ladies and gents.
I have a set of 823 that came off my 6.0 truck motor that I am currently building for my 99 trans am. It is going to be a mild street build with maybe just a little giggle juice. It's getting summit racing forged rods and pistons but staying stock crank. Cam is yet to be decided. between a btr, or a texas speed.
my question is. How do these heads perform after a little bit of work? I plan on having the same machine shop due the heads that is doing all the block work. is there anything specific I should look for or have them change or machine?
thanks in advance.

Those heads are great as-is.
Having said that, all you really need to do is a good multiangle valve job and do a bowl blend.
These two things are 80% of a good port job as far as results are concerned

Thanks for the input. I just sold my old ls1 today to a buddy so the cash from that is going into all the machine work so I don't want to spend any money on anything not needed. and I can build a decent lower end but when it comes to head work I am completely lost in the sauce. I am also lost in the sauce when it comes to the search function on the forum hahah
