I have an iron head part number B-1262098. They are what i am told, ported polished with bigger valves and they are o-ringed. The exhaust valve measures 1.775 and the intake 1.498. Are these bigger valves? Also, im looking to make between 700-750 HP. Would it be safe to use these heads or should i go with the champion Iron heads? It looks like the champion heads have a different set up for the rocker shafts. The pedastal the shaft sits in on my heads is flat where the champion heads is round. Does this matter or does the champion heads eliminate the use for the block i have attached to the rocker shafts? They are TA performance 1.55 rollers. Thanks alot. You can see my heads in the stage 2 section under "what heads are these?"
