I got a question that I cannot find a answer for so I thought I would post it up here to see if anyone else had an answer..I am installing a Edelbrock Exhaust Cam 4730 in my GSR B18C1. Now I was told that this cam is similar to a Type R exhaust cam, and I know that the Type R uses a Double Valve Spring set up on the exhaust side that the GSR does not because of the bigger lift. So I am wondering if I could put in the Type R Exhaust Valve springs in with this cam and be ok. I have some laying around and if it works I will just put those in with this cam, otherwise I really don't feel like spending $300-500 on valve springs for the little amount of power I am going to gain from it. And Im sure someone will ask why only the exhaust cam, is because I am supercharging it, and the best set up is a GSR intake cam with a Bigger Type R or other exhaust cam.

 

Valve springs are only like $150.

 

+1 i got my blox with titan retainers for 160

 

Yes I know there are cheaper valve springs out there but edelbrock states u need theirs otherwise type r springs are like blox from
What I've read

 

The Edelbrock cams aren't that big. But if you are worried about it then source a heavier spring. Like Suptertech's 80 lb seat pressure offerings. They are still affordable and most manufacturers offer multiple spring rates to choose from.

 

Would the dual valve springs from either the intake side of the gsr or the duals from a type r work?

 

yes, just find some used type r's if your on a budget.

 

^+1 I just gave some away like 3 weeks ago lol.

 

Yes it will work. I put inners in my exhaust side for my gsr...
