EssexVXR8 said: Fouls timing cover in several places, std cover Is it a standard pump or high volume ? SDPC are doing front timing cover kits for the LS2, including sensor, gasket, bolts, oil seal etc for $85 ! Bargain that. I fitted a Melling HV pump on mine which is a pretty big pump ( and I know not needed ), and also using a duplex chain so the pump is spaced out. Even it only required a little grinding on the pump and cover to make it fit, although that was an LS1/6 front cover.

BTW we used to hear the same statements with regards to the stock camshaft despite comments and evidence to the contrary.
If your power goals are mild I would however accept your statement. Though the use of an iron block would suggest otherwise?

Better flowing heads do work with FI flow is flow !!! And less pressure to make more flow is better is it not ?

If I remember correctly Gareths engine on the dyno produced no more measurable power with AFR heads over std

EssexVXR8 said: If I remember correctly Gareths engine on the dyno produced no more measurable power with AFR heads over std Yep, but be careful the conclusions you draw. Rotors spinning at x rpm push y air. Swap heads and at X rpm Y air is still pushed, no change! But pressure & temps should drop etc due to less retriction. Same deal as a cam in effect. Of course with PD blower without spinning it faster no more air is entering anything, hence obviously your statement above is the result. NA will show gains because it is not similarly restricted. So better heads will let you push more air more efficiently.

There is a theory that says FI engines benefit from bigger exhaust valves or more duration/lift on the exhaust side to help the extra gas escape. Makes sense when you think about it. Heads and cams intended for NA will not help you. Also, to be fair to Richard, I thought it was an iron block too when I saw the red paint.

Could have been an LQ9 etc. Anyway heads for NA will help, heads are heads for the most part, they are not normally differentiated except for chamber cc. Cams of course should be optimised for the intended application. Also its not theory its practical fact.
