I believe you have 462624 heads. Should be easier to look up.

They don't flow good.
Thanks 84. If you say the #'s are 4626 that's good enough for me.
I'm so new enough at this that being "easier to look up" is still difficult because of not knowing where to look up.
I want to put in Dart's 180cc pro platinum heads which are better of course.
I'm wanting to know how much better.
Thanks again, and where do I look?

Just noticed stew86's reply.

I was in a limited coverage area last night. Id normally look it up myself and post a link. But I know they're weak. Weak casting and flow being honest.
Thanks 84. Your correction and Stew86's treasure map lead me right to the answer.
L83 462624: Port volume 158/ chamber 76/ .500 lift 196/140
Dart Platinum: 180/ 64/72 257/172
Undecided on chamber size. Street motor build. Comp cam #252FI HR13/ lift .550-.546.
Stock plenum, TPIS headers, Pistons, yes pistons she will have pistons. What kind?
Flat? Small dome? The motor builder will know.
From my position on the learning curve, this looks like fun.
Thank You!

With a small cam like that I'd go with the 72s. Don't have to worry about fuel octane then.

What I found interesting with the link of cylinder head flow, the owner of the site does say he compiled all the data from all sorts of sources. i.e. internet, magazines, publications etc. With that said the flow numbers as listed for the 462624 heads came from CF member Joby.
Thank you gentlemen.
I see the motor man in the morning.
If November 3 goes well we will launch.
If gas goes to $65/gallon with AOC as secretary of energy,
never mind (as Roseann Roseannadanna might say).
