Here is my own personal 5.7 eagles with a worked chamber on the left and a stock chamber on the right.
Any power #'s with these heads?
I ran out of time to flow the other heads today so hopefully tomorrow I'll get to them.
Novawagonmaster over on LXforums is going to crack a 10.99 with an all forged 5.7 in a 4000lb Raceweight Challenger soon enough with the same heads. This is a mid port head (stage 2).
He is within a tenth of his goal.

Sorry guys, long dyno day and no flow #'s on the hemi heads. I will have them tomorrow for sure. I'll have pics of the 6.1 and early 5.7 heads too.
Plan on sonic testing the block tomorrow if I have time.

The 5.7 being a 3.92" bore and the 6.1 being a 4.05" bore, do you see any real drawbacks using a 5.7 block besides the obvious lower cubes? Was wondering if there would be an issue with airflow around valves, especially if stepping up to larger valves like in the 6.1 heads or the newer Apache 6.4 heads.

There is a guy on the LX forum that has a stroker 5.7 that had ported eagle head running itnto the mid 11'w he switch to a set of ported 6.4 apache heads and went .2 quicker in the 1/4 mile. Keep in mind his block was bored .020 over. A member Matt on this board posted the apache head on a standard bore 5.7 and the intake valve looks close to the cylinder walls

I run a short filled 400 block in the street for several years, just a tad above the bottom of the freezeplugs. Had no oil cooler and no oil temp gauge. And also no problems with a 3.75" stroke. I also run a RB block filled close to the tops of the freeze plugs, 4.15" stroke, no oil cooler or gauge. In that case the oil got propably too hot in continuous driving on the freeway, the oil pressure dropped after about 1/2 hour of driving from 60-70 psi to 30-40 psi level. Swithcing to synthetics made the situation better, there was even some pressure at idle. I kind of figured that as long as the fill stays below the piston ring travel, there is zero problems, and as you raise the level, the more problems. Oil cooler is definitely a good idea, and should let you use even a realtively tall fill in a streeter.

Here are some pics my brother took yesterday showing the port sizes on the eagle heads vs the early 5.7 heads. Crazy the size jump on the eagle. I will start clean up on the eagles and hand port / polish soon. Is there roller rockers avail for these motors yet? The eagles have only 40k miles and the valve tips are beat up awfully bad from the stock rockers.
