Possible cam install

you can cut the intake if you want, but if your taking the heads off ,let the shop cut the intake side of the heads instead ,and set them up with new valve springs.The old valve springs would have to be load tested and then set up.
This will cost you more in shop time and they wont be as good as new springs.
The new springs only have to be set up at the correct installed height, to get the correct closed spring presure.
FOR EVERY .010 IN. MILLED OFF THE HEAD (OR BLOCK), YOU HAVE TO MILL THE INTAKE SIDE OF THE HEAD .0095 IN.

TO 340DART \\\\\
ON A 73 CC 360 HEAD ( OPEN CHAMBER )
EVERY .0048 IN. MILLED OFF REDUCES THE CHAMBER VOLUME BY 1 CC.
SO TO MAKE A 360 WITH 73 CC HEADS 9.5 TO 1 FROM 9.0 TO 1, YOU WOULD HAVE TO TAKE OFF .0228 THOUSANDTHS OF AN INCH.
ROUND IT OFF TO .029 IN.
I CUT MY HEADS .015 AND USED A .026 THIN HEAD GASKET.
FOR HEAD GASKETS IT'S ABOUT (.020 IN.) FOR .25 IN COMPRESSION.
MY HEAD GASKET IS .014 LESS THEN BEFORE SO
I HAVE AT LEAST 9.4 TO 1 BUT MORE LIKE 9.45 TO 1.
ZAKIMOTO WILL HAVE A LITTLE OVER 9.8 TO 1
I REALLY DONT KNOW WHAT HEAD HE HAS ,BUT IF IT'S A 73 CC HEAD THEN THATS A GOOD GUESS.
IN THE END IT'S HIS CAR ,AND HE NEEDS TO CHECK EVERYTHING OUT AND TELL US THE FACTS.
I'M NEW AT THIS HOLE GAME OF TRYING TO FIX A CAR OVER THE NET. :idea1:
