So Chief paid $2800 and pulled them out of the box, bolted them on and runs 3.9s as is. Impressive

E-heads are impressive....most bang for the buck head ever made for a Pontiac..... I know guys that put a chit ton of effort into hi-ports and then a crap ton of money into Tigers just to try and keep up with E's.

I know guys with e-heads on spray that are more than second slow than me, what's your point?

Our experience was the switch to Tigers from Edelbrock heads was an immediate 80+ HP on the dyno. Once tuned as good as we could get it, 102 HP better. Same camshaft, same intake except for spacers the Tiger heads required. Early Edelbrock castings hand ported by me vs very early Tiger heads also hand ported by me. Peak flow was about 40 CFM greater on the Tigers. Nothing against the Edelbrocks, they served us well. The Tigers have more real estate to work with, taller port, less water jacket and pushrod holes in the way. Your experience may vary. Smart people are running very fast with all the available heads. It mostly depends on how much work your willing to put into them.

Don't mind us we're just talking non-sense But on another note, are the Tigers similar in airflow to your RAV heads? |

I disagree.....your signature says "7.98 quickest Pontiac door car in Michigan" You do know Mike went 7.96 (naturally aspirated E-heads) and his car is still together and in Michigan??
So hi-ports with a blower and trying to catch the naturally aspirated E-heads....your statement has little merit. |

If you notice, I did edit my post to be more correct. Peak air flow on our Ram Air V heads is potentially better than the early Tigers we were using. Our Ram air V heads were really fun on the flow bench. The most amazing thing about the tunnel port head is it never stops flowing, all the way until the retainer hits the valve guide. It continued a slow climb to 1.3" of lift where I stopped. It never makes that shrieking sound a head makes when it is done or starts to tumble. Even with that giant obstruction of a tube in the middle, it keeps flowing. 430 CFM @ 1.00" We run a pretty mild cam, only .840 net lift. Just over 400 CFM at that lift. Our Tiger heads were pretty much done at 1" lift. Also around 398-400 CFM @ 1" lift. The Tiger heads had a more "angry" sound on the bench and the flow was around 370 CFM @ .700 lift. Slow gains from there. But we ran a much more aggressive cam in that Grocery Getter engine, about .930" net lift. So similar, but different. I am obviously very intrigued by the Ram Air V heads. I have done a couple sets of Ford Tunnel Port heads as well. One set in a Cobra Kit car with a 427. That thing screams to 7500 RPM's. Also, the cylinder sizes were different. The Tigers were flowed on a 4.375" cylinder we were running and the Ram Air V's on a 4.250" bore we are using now. That would also effect the flow numbers. Sorry I don't have a perfect apples to apples comparison.
