oversized valves are a waste of moneya nd only cause major issues with valve to valve contact




contact me via pm if intrested in some headwork done

Correct, and if not done properly can actually slow down port velocity. I honestly don't see why people want o-s'd valves on these heads...the only time they really produce viable numbers is with a large boost setup, or a rev-to-the-moon larger-than-stock displacement (i.e. above 2 liters and 10k+rpm). A well done port job will produce more gains for your money than o-s'd valves will.

well the problem is people install oversized valves but dont port to the larger valve basically making the work worthless



not to mention any cam that has any kind of lift will kiss os valves




stock and a nice valve job


works

if you get any real cams you will need to up the compression to make any use of them. you gotta match the comp. to the cam and size other parts like IM and TB based on where you want your powerband location.

Not really. The manifolds are ITR-clones, and the GSR units are completely fucked as it's just a reflanged B16 manifold which causes abrupt transitions at the flange rendering the manifold complete dogshit.

Their TBs stick and generally suck.

TBs:

Best is a correctly bored stock TB which come up to 65mm, then Professional Products which come up to 68mm, then you need to come up with an adapter plate to run a 70+ mm LS1 or Mustang TB as most of the Honduh offerings suck or are seriously overpriced.

for that price you can get a edelbrock

edelbrock again is meant for big power set ups
