I would like to know what are the best OEM BB cylinder head castings? I am considering building another 383. Thanks in advance.
Best as in for flow, for porting, stock or ???I would like to know what are the best OEM BB cylinder head castings? I am considering building another 383. Thanks in advance.
Just get any head and clean it up. Make sure to call a machine shop to see how much it costs to do stuff possibly needed, like guides, surfacing, valve job or new seats...Thanks, that is good info. Sounds like there is not much difference in the castings. I am looking at doing a budget build, so I figured it would make sense to start with the best stock used heads I could get.
For a “budget build”, the best heads would be whatever castings you find that would be suitable for the application(passenger car/light truck heads from 65-78), that require the least amount of work to make them usable.
I’m not sure what machine shop costs are like in your area, but where I am it’s pretty easy to spend close to Stealth Head money refurbishing old BBM factory heads.
And with the quality of todays gas in sunny, hot Florida, look better all the time.Wow, I just looked the Stealth heads up, I didn't realize they were that reasonable. A pair of fully assembled aluminum heads for $1200, thanks!
I wonder if he's flowed them all on multiple benches ?According to Jim Laroy, (@IQ52), the 906 heads have a slight advantage for flow over all the rest of the factory castings. I believe he is correct.

lolNo he hasn't.
He is a clown.
Ignore him.
Yeah right, I read your posts & threads and have learned alot, There's no clown in you sir. I did however think that was a legitimate question since benches seem to give different results on the same head.No he hasn't.
