dont mean to be mean bro, but you keep posting the same type of questions over and over again. seems like by now you should know the most about all of us. people get sick of answering the same question and feel you dont value any of thier opinions if you keep asking questions about every head, cam, intake for a 350 sbc. like i said not being mean just look at the past couple pages.

there is so many books and different info on heads for chevys. all you need to do is go to yahoo and type in "how to decode chevy cylinder heads" you also posted the cam sound question twice. look at the past 5 or 6 pages. you are on all of them at least once for the same type of question. i agree that we are here to help but you cant expect us to do all of you engine research for you. chevy motors are considered the most popular motors ever made. there is an abundance of info on them.

you already asked about the 336x heads in your post "help" how much more info do you need and how many heads do you have?

i also have a set of 336x's that are in the machine shop that are going on a mild 350. I have not found any info such as flow numbers so far. not as good as camel humps but probably still flow decent being 71 heads. i've been told there as good as any factory 76 cc head.

yo i am not making a big deal of this. i am just saying you keep asking everyone how will such and such increase performance and whether or not a certain combo is good for a truck. you have recieved great responses and tips. how much more do you need?no one knows for sure unless you run everything through desk dyno. if someone doesnt answer than maybe they dont know either. so if you post it again people get angry and wont answer. im just making a point. if there is no info on something what will make the next guy so sure he knows what it is. i dont want to blow this out of proportion. i am not knocking your questions or attacking you. i respect all my fellow rodders.

i am no expert, so no body bite my head off. But the key is 76 cc heads. I had some on my 383 stroker and wished i had the money for some good 64cc's. Just my opinion.

64 cc heads will bump compression up on a stock engine originally equipped with 76 cc heads. However, many mild 350s need to run on 87 octane. 64 cc heads will put a flat top 350 into high grade gas territory. Dish pistons may keep the CR low enough depending on dish volume. If this is the case then i'm sure the 64cc heads would probably be better. i have 10.3 CR on my 383 with performer rpm heads and i love the high compression. But for a mild 350 that will not see the track and must run on 87 octane, 64 cc iron heads are not reallly an option.

400 SBCs have higher compression compared to a 350 if you use flat tops. I use 64cc heads on my flat top 400. It makes it about 11:1. I used my Dremel tool with a high speed steel cutter and smoothed out the chambers. I removed the sharp edges that can become hot spots. Hot spots cause detonation. Anyway, my car doesn't ping and I can only get 91 octane where I'm at. 64cc chambers are more efficient. get the 64s and clean them up.
