I will attach some pictures off these 045 heads I just received with a lot off BBC parts I bought , can someone have a look and give me the scoop on them , I thought all peanut ports where small oval these are large oval port and have pass stamped in them, and looks like also someone smoothed things out inside intake ports, does anyone think they might ok to use, I know and have read all about how bad these small port small runner heads are but these look different on the outside,
Looks like just a standard Oval Port BBC head, someone has done a port match at the intake face and blended down into the port a bit. Standard passenger car or light truck Oval Port, not the heavier truck Peanut ports.
Last pic you posted just shows some machining chatter in the throat cut is all, left from the lower cut in the 3-Angle valve job.
. The 'pass'enger car oval ports heads often work better for mild street BBC engines than the too big rectangular ports that came on highest HP factory engines... give a fatter torque curve... better MPG...
. Even the truck BBC heads with the little oval 'peanut ports' good to up to about 450 HP, since even those ports are actually big compared to SBC head ports...

. Yes, the -045 heads should work great... along with a mild cam... 214/224 - 220/220 range... should fry the rear tires off with a 3.90 rear end... will be hard to keep it down to 375-400 HP...
Did you miss he said dished pistons, Buzz?? With open chambered heads ain: Be lucky to make 275HP, won't be good at anything other than gulping fuel. Be outrun by the average 10 year old Toyota Camry.
