10's on $5,000 ?

I've completely lost my interest in porting. I've done it so much, the last 3 sets of heads I did weren't fun...

Sooooo, you’re saying there was a time when it was.....”fun”?

From a strictly “flow” standpoint..... the ootb 265cc SM BB heads flow enough to go 10’s....... but that doesn’t mean a little tweaking wouldn’t help.

If you get the weight down, 10’s isn’t hard at all.
Under 3300 race weight and 500hp, a good converter, and some hook.
