Basically he agreed that the SS was murdered beyond REASONABLE repair. We put my cam on his Cam Doctor machine and it checked out dead nuts on the money. He doesn't believe there's much reversion. We did 13 pulls and the intake runners are pretty clean.

Showed him the flow numbers and said throw that away. Yea, they look lousy low and mid lift, but don't live or die on numbers.

So... what he hated that CAN be fixed is how they over-cut the back and sides of the port. Light bulb shaped. My best option is to ditch the heads and buy a pair from Rod Bloomer.
My other option is to epoxy the back, sides and part of the floor to give the air a straight shot into the cylinder. He felt there has to be huge turbulence the way they are now.

Showed me some AFR, Dart, and TrickFlow heads. No lightbulb shaped ports in those

He used modeling clay to give me a sort of "template" as to how to shape them, and gave me the part number for the epoxy they use.

I think I posted 4 pics as they are and 3 of how he wants me to change them. keep in mind, the 3 pics are done with clay and rough but I get the idea.

Also said keep the cam. It is ground correctly and SHOULD make more power. Just changing cams "will not fix this".

so.....at this point, I'm going to goop 'em all up, get them even and smoothed and give it a shot. If that doesn't help, i guess I'm selling some guns and buying a pair of BPE's.

If the epoxy he told you to get is a 2 part that when mix up look like a military green, then let me help you out.
altho this stuff sands nicely your finger tip will be wasted before you ever get one head done.

Get a black nitrile glove(thin rubber gloves)
Get some 36 grit sand paper that a body man would us on a longboard(the ones that have sticky on the back of them.
Get some super glue.
Install one glove on hand, tare of small pieces of that 36 grit sandpaper and super glue them on all 5 finger tips(the glove not your finger.)
Now it real tough to get in there with a glove full of sandpaper with out messing ups things like seat angles.
Remove sandpapered glove and pull the pointer finger off of the glove and then reinstall on you finger.
Now you have great control over the sand paper and it don't fold up.
Now you can get into the nooks and crannies and make a great shape. The good thing is that if you go to far......you just mix up some more.
The stuff i us is called Z-Spar and was originally used to patch up boat. It will set up under water.
takes about 12 hours to set up when it's cold outside.
It mixes up like putty and acetone or lacquer thinner work good to thin it out so you can flow and shape it better. I prefer Lacquer Thinner.
Clean the port out with Lacquer Thinner, scuff the port area and then clean it again. Clean Clean surface is a MUST!!!!
A real Thick putty knife or gasket scraper work best to mix it up. It's like mixing up TAR!
