opinion on stock heads

[blk00rt]

I have a failry stock 360 motor with a ld48 intake, headers and ignition system on it, I just recently purchased a eddie cam the bigger one of the two. I know it wont work with stock springs so would I be better off waiting until I can afford eddie heads to go with the cam or change out the springs on the stock heads and run the cam with stock heads. This is pretty much just a cruiser with a little more poiwer.

No need to go to Eddy heads just cause you got a new cam. Check with the cam manufacture and get the correct springs for the cam and rock it as is!
Thats what I would do anyways...

eddie lists their recommended springs so I will probably go that route..
thank you

at .510 valve lift on the exhaust on stock heads, you better check retainer to valve- guide clearance and retainer to seal clearance, as its going to be close. on the intake you should be fine though. if it doesnt clear, you will wipe out your cam lobes, plus the exh. seals. check the clearance using a soft spring, compressed air and dial indicator. you need approx. .100 in. between the seal and the retainer at max lift on the exh,so you want .510 +.100=.610 when the valve is closed.you could check the clearance without swapping the cam and/or springs, only the soft spring. if you find out you dont have enough clr , then you need to remove the heads and have them machined to shorten the guides. i believe the edelbrock heads would swallow this much lift without modification, so, if you have to machine the stock heads and planned to use edelbrocks anyway, why not do so ?

thank you I did not think about that...
I will have to measure it and see.
