RHS or EDDY

I completely disagree about the cracking.
Lame.

you guys think telling someone to go drop 1300 on new heads so he can have quench at 9.5 comp is cool or helping?

Ive seen some of you cats ruin your factory heads by over porting the short turn, yet...there are no cracks.....

Hell...my j's flow another 30 cfm over that & port volume out at 186-187cc....NO CRACKS
Ive milled .060 off of the decks.....NO CRACKS

Its one thing when we're talking factory magnum heads, but the j's are no more crack prone than any over priced after market head out there.

Why is it that when someone comes on a car site wanting a lil more umph, every web genius on the planet comes out of the woodwork telling him to go spend over a thousand dollars on heads that still need to be worked...

Change that cam!!!!!!

Tune it, or have it tuned by someone who really knows a lot about it!!!!!!

Dont spend 1300+ for 'maybe' 20 hp!!!!!!!!!!!! [everything else the same]

You'll need more parts to make to realize the potential of that after market head.
AND.... next thing you know....you'll be back asking why you dont really feel that much of a diff, and next thing you know....the same salesmen will be back telling you to buy something else to make'm work.


I see a couple options...
1 fix what you have, they will go 270cfm@500 fairly easy and shouldnt cost more than 300-400 worth of porting, and then cam option..
2 ...just up the cam and make th heads work harder, get the mid lift where the peak flow of the head is 'HENCE THE FLOW TEST BEFORE HAND'

OR 3, quit messing around and go buy some full ported aftermarket heads along with a 'at least' .550 lift/288-298 dur 108cl cam and of corse change the pistons for some 'min 10.5 comp/zero deck height' and then the that magical closed chamber will actually do something for power that you can feel.

Back in the day when I was starting out...if I was to listen and follow the advice im reading here today....I would be broke, just as uneducated about engines/tune, and pissed off lookin to pound on someone's noggin.


btw, this is where lack of interest comes from anymore, guys I respect...who for some reason stopped make any sense.
