There was an old thread some time ago where valako flowed them without cheater pipe and was not as claimed. It was either these or the 315's. I will find it and post link.

Take one off and give it to bills dad Tim.
His friend with the cam doctor also has a flow bench and he flows all our stuff.
Very reasonable!

I know he flowed an AFR head some time ago and it didn't flow the numbers advertised. Not sure what head, but it was an out of the box AFR.

Also, depends on what cylinder you flow.

I may if I decide to get that serious about changing combo, starting to gather facts...

If you really want to maximize the heads, have Mr. Klein put the full port and blend to them. Have him do the intakes too.
Let bill set them up and have them flowed.

Have you talked to different cam grinders and gotten vastly differing opinions on cam specs? I.E the 108 idea.

not gonna go crazy doing all that, but I feel cams can really help...as far as the 108 thing, came into my head because I did my Ford engine years ago on a 108, ran way better then expected, cam motion cam..Bill told me to do it for more TQ

I'd consider putting solid rollers on the cams you have if you want to try something without getting crazy.
Probably pull more RPM

what would power difference be? don't really need the rpm, but more power, part of the reason for a cam change is I am worried about long term life with these, others have had issues with similar grinds..

All the more reason to take the heads off and evaluate what's been going on and if your worries about the valvetrain are a real concern. You have enough time on the engines that, if the cams are doing damage, you should see evidence by now.
