mornin hass! how much did the intake flow on your heads?
OK after checking this out apparently the Pro comp heads arent the same as Pro top line or Pro action heads , Pro comps are china made and the others are made in Australia. Thats why I couldnt understand all of the squacking because I was impressed with the as cast condition of my Pro action heads, they flowed 375cfm at 700 and 390cfm at800 , at 28* right out of the box. Oh, that was with 2.3 intake valve and 1.9 ex. After a prof. port job they still just made 400cfm although they picked up alot through the mid lift #s which means more than peak flow # s. got to go to work, be back on here this evening.

i'm sending the heads over to ronny sealager(sp?) this afternoon to be flowed. if they flow at least 340 intake and 240 exhaust, i should be able to get at least 750hp with the current cam.
every dyno sim i run still has this na motor making 40 more hp & tq than the blower motor i ran last season, same cam and heads.
