Killer deals on Gen1 heads are everywhere. A while back I saw a set of heads like mine WITH shaft rockers for $1500. DUH thats a no brainer right there.

If this is so cheap why don't everyone do this? One of the main bottle necks for us LT1 guys is the head market.

ok im going to play dumb on this one.....what are you all talking about here? reverse flow what? i saw a car at the car show once where he had single motorcycle carbs on each exhaust port of the heads and straight pipes out of the intake manifold. it was unique and couldnt quite figure out how it worked, but it did. is that what you are talking about when you say reverse flow?

Reverse flow means the heads are cooled first and then the block, which is opposite from standard SBC's.

I don't know how many sets I have done...and would be sick to think about it... but it IS a very common conversion.... for some reason it is not talked about on the internet though...
