Twisted Wedge RR ?

[sweet88gt]

Ok, this is a question that Im having about Harland Sharp 1.6 RR and a set of Twisted Wedge heads. Im trying to use the stock valve covers and have ground the oil baffle out but still think I might have clearance issues. Has anyone run the same set up and how did you make it work. Thanks.

Thats wacky, I was just about to ask the same question except with 1.7 RRs. I called to order some TW's from Summit but the sales guy said I had to use tall style covers which I dont want to do, but he did give me the tech number to Trick Flow so I could ask them. Unfortunately they are closed today, Baaaaffffffkkkk!

Trick Flows tech support is very good. Ive called them a couple of times and have been very helpful. Im right in the middle of a head cam intake install and want any info I can get. I think if I grind the webbing around the oil baffle as well it may work. I just wanted to see if anyone had done the same.

I'm pretty sure 1.6 rockers will fit under the stock VC's. I know of guys running like that. 1.7's however will probably not. I had to order some taller VC's to clear mine. Now I just hope the upper intake clears the taller VC's, otherwise I have to throw on my 1" phenolic spacer. Then the hood might not clear.

I have a 1/2 spacer going into my setup because the Twisted Wedge has a raised valve surface of .350 inch. I was hoping that that and the grinder would solve the problem. I might have to bite the bullet and purchase vavle covers and just get over it.

My intake is already rubbing a little against the hood so a spacer isnt an option right now, as I am going back to school soon and am only going to make so much moola this summer so I cant buy a hood too. I wanted to do the stage 1 cam too but just cant squeeze it in the budget so I am just going to throw on some 1.7's with the stock cam. At least I was hoping to.

I called trick flow and they said that 1.7's willfit under the "trick flow" brand short covers.

Phew, thats a little reassuring. Do the short covers come with a filler neck or do you have to modify them somehow?

 

[D347643]

no filler neck at all. you can drill a hole and put a breather in though thats what i did. I plan on switching to 1.7's when i port my heads cause ive heard that with my combo 1.7's would just give me more lift but my heads wont be able to flow enough for huge benefits

TW's reach peak flow at .500 lift on the intake, any extra lift just wastes energy opening the valve and wears out the valvesprings faster. A cam with more duration but that still peaks at .500 lift will also give you more power without having to port the heads.
