I just cant decide on whether to go ahead and get this intake ported and the outside polished, or run it as is and wait till Richard gets done with the L92 program and slap a set of those on with a carb intake and get that one ported and shined up. They would flow about 70CFM better then the 317s

They might flow better, BUT what about velocity, I am not sure one way or another, but that might be something to consider.

Who needs velocity when you have an 88mm turbo pushing air through it. In a smaller motor I may be concerned about in town driveability but I think I have the CI to be alright, the L92 stuff is relatively unknown right now thats why Im having such a hard time deciding what to do with my Vic Jr since this summer I may swap to a set of WCCH L92 heads. Richard said he isnt oging to port the intake on them very much at all and mainly focus on exhaust and the chamber. If GM puts these heads on a 6.2L I think my 6.8L can handle it, Im going to wait and let osmeone else be the guenia pig for that stuff. Ill see what this motor and 15#s of boost gets me, if it aint where I want to be then back to the drawing board.

I forgot you were going FI... , As far as the L92's, you'd probably need a set of pistons with the valve reliefs in the correct spots and correct size for those monsterous valves too.

All of those things will be answered here shortly, I dont think the valve reliefs are going to be a problem, atleast I have heard of any problems with it yet. On paper they look like damn good heads so we will just have to see whats in store for us in the next few months. I know one thing, if these heads do work well, 317s arent going to be worht ****

I have an extra set of the 317 paper weights too. Is the deck on the L92 any thicker than a 317? I wonder how the head gaskets will hold up compared to the thicker decked Edelbrock? I originally wanted to go with the L92 head, but at the time when I bought mine, there were not too many in use. I was scared of the offset rocker and the valves not fitting in the dish of my pistons. Is the L92 VicJr already available?

Once you reach a certain power level, things like O-ringing the heads become more of a priority than more CFM.

GM makes a carb intake and someone else but not edelbrock. The edlebrock 245s you have will be a much mroe stout setup and keep headgaskets alive alot longer. I want a 10.80 at full street weight, Im hoping this setup and and 15#s will be enough, Im ready to move on to something else.

Just out of curiosity. Did you have/need/want to change your ring gap due to you going FI? Would it make much difference if you didnt change it?

They were already set wide due to the 400hp he was planning on sprayin on it. They should be fine.

Yup they are gapped at like .028 top and .020 second IIRC, for the large shot of nitrous I was going to spray, I knew eventually I would go FI, thus the design of my piston so I could throw on a set of 317s to drop the CR to low 9s and haul ***.
