which heads to use?

[race-rodz]

link doesnt work for me.

im curious about the 327 crank in a 400 block, if you are gonna use "production" block and crank? the only way that comes to mind is to use a medium journal 327 crank(350 mains) and bearing spacers in the 400 block.

this sounds like an rpm style combo, similar to nascar's 358" set-up, but only wanting to turn it 6k-7k, seems kinda pointless.

i say run a 3.75 stroke(400) in the 400 block, with the afr 195's, and your target should be pretty easy to reach. as the saying goes, there is no replacement for displacement.

Is this the '350 that Chevy should have built' version? Forget where the article was - maybe AFR's site?

OK so what heads are good. I am curious myself. Me personaly if I had the money I would go for the AFR's.

I really like the Pro1s they are cost friendly and post good numbers, but what do I know.

[JUSTANOVA]

well in jegs the afr's are only about $100 more. I am just looking for opinions/suggestions from some of the more experienced guys as to wether or not the afr's are better/same/worse than the darts or brodix or pro's/cons of either.

Another option is the new Partriot Performance heads: http://sites.reachtheworld.tv/waterN...06263&DID=1225
They just made some good numbers in this thread w/ info about them: http://www.ls1tech.com/forums/showthread.php?t=438350

or clevite makes a "thick bearing" that doesnt require the spacer and aids in the heat transfer to the block.
