What to do? Need flow #'s for heads?

Bought this car a week ago. Need to order a pcm4less since I can't find a local dynotuner for the lt1. The guy can't find the flow #'s. Lloyd Elliot did the heads years ago according to the guy it was when he first started doing em. Thanks for any info. I know it's not lsx but i figured this was semi universal question.

if you can't find the flow numbers, then the guy at pcmforless will need to take a shot in the dark.

well just responded to Jeff Creech and he told me to get the car dyno'd and send him the sheets and he can tune it pretty close with that! I think thats what I am gonna do...

Your basically pissing in the wind if you try to guess your flow #'s.Castings change here and there so almost every head is different unless it's a aftermarket deal that is cnc'd.Plus if it was in someones beginning of there career God only knows.

oh and lloyd e-mailed me back and said "the heads probably flow about
250-255 on the intake and about 170 on the exhaust. They probably have
about a 185 cc intake port" and the heads have the stock valves.

So cam is going to do a tune and then i'll do a dyno and then send the pcm and dyno sheet back to him for final tweaks! Both Lloyd and Jeff are great and really helpful.
