New member here,and I will admit that in most cases,I know just enough to get me in trouble,so please understand my (sometimes dumb) questions.This is my first time messing with a bbc,much less messing with anything non-stock.My block is a Gen.VI 454.Crank and rods are from a 502,so essentially I have a 454HO bottom end for starters.All in the m/c getting prepped,bored,etc.Soon it's gonna be time to select the pistons and cam.SOOOoo,the other half (heads) of this engine are Chevy Performance #19331424,2.19"in.valves and 1.88" ex.valves.

I've been researching and it looks like the heads are identical to/built by Edelbrock.Further research indicates the sparkplug holes have been relocated toward the center of the chamber,so,no problem as I've found SRP's that look suitably applicable to these heads:

Now to the camshafts I have narrowed down:

BBC 454 to 470 CID with GM Edelbrock Roval Heads to a max of 6000 rpm - Clay Smith Cams

BBC 454 to 470 CID

Keep in mind that there are 2 versions of my heads-2.19" in.valves or 2.25" in.valves,and both would have 1.88" valves.

Would like some input in a combination.This is going in a "69 El Camino,12 bolt posi w/3.42's,TH400 w/2000 stall that will mainly be a street car.Manners are mute,but would like reliability and strength.
