I got a set of stock heads and an intake from some one for nothing. I ported both. Cut the box open on the intake, ported, got it welded up. Ported blind (oo) when it was all done, I scraped money cutting grass to service the heads. 3 angle valve job, decked .030, new seals, .060 shims under the springs, ect... $200.00. I put it all on, the car ran WAAAYY faster. I lucked into some money got a 65mm TB. I already had 1 1/2 long tubes, 2 ch flows, 3.55s,k&n,fuel reg.,sub frames,4cyl springs all 4, muffler shop H pipe. It ran 13. 85 @ 100 before the heads and intake. 13.09 @ 105 after. Now, I gained 7 tenths, not knowing crap. All I knew was things are tight, my babies need to be fed, And we AIN'T GOT NO MONEY FOR THAT DAMM CAR. Fellas, port your stock heads. We all don't have $1000.00 alocated for alum. Have fun, do it anyway. People told me, Your waisting your time, now I'm waisting them. Who is it that said "come to the track, you might learn somthing?"

I too shaved off 7 tenths, in a different way, i wish i could have my car down long enough to have the heads hogged out, but rely on it everyday for now.
Also i see you are pretty supportive of welding torque boxes, i am going to do this soon, since i can see a crack starting to appear in the pass side box, i give all the revs i can off the line (with crap gears) to get a good 60' i have a friend that is a welder, i am calling him this weekend, do you do this for strengh purposes only? or will the rear actually transfer power more accurately?

thnx workcar, and keep the wheels dangling
