do we have dual or single valve. and if single should I get dual?
That is a pretty steep price for E7 heads. I'd dump a couple hundred dollars on a set of P heads before I'd buy ported E7s. I'd love to see those heads flown on an independent bench....Thumper Ported E7s (219/155 cfm)
So that is a full head right their?
- Performance Vassco dual springs, moley keepers and retainers
- For cams to .600 lift (not included)
- Stock valve size for the Killer low end throttle responce, and the flow for the mid to top end
- Optional - Machined for Screw in studs and guide plates (for adjustable valve train) - Add $100.00
- Optional - Roller Timing Chain Gear Set w/3* Key way (for advancing /retarding Camshaft) - Add $64.95 + shipping
- $695.00 + 100.00 refundable core charge
700 for e7s FTL... thats a lot of $$ for minimal cfm. 220 cfm is stretching it a bit to me thinks.That is a pretty steep price for E7 heads. I'd dump a couple hundred dollars on a set of P heads before I'd buy ported E7s. I'd love to see those heads flown on an independent bench....
I ran an f-cam with stock springs on an e7 with no problems, but I think I was lucky. I never revved past 6k and usually shifted around 5600-5800, but....I WAS LUCKY, and prolly a lil ignorant too.I'm still pretty sure I'm going with the gt40p heads. I'm still wondering if I need to replace the valve springs because of my fcam. Can someone let me know. And if so what size?
Darrel Im running the comp beehive valve springs. I have only heard good things about them. Beehive valve springs have been known in the industry as having a lower mass at the retainer end thus allowing for better valve control. Do you think this would be a good spring for flattus78 to use. I think its a good option. Any opinions on this?You need the proper springs for the cam you choose.
The are nice for mild set ups, but it is more of a marketing ploy than anything. You have to use their retainers, locks etc...Darrel Im running the comp beehive valve springs.

Me thinks the same as you thinks.700 for e7s FTL... thats a lot of $$ for minimal cfm. 220 cfm is stretching it a bit to me thinks.
You still need to use the proper spring. Beehive is a style. They still have many different spring rates.Darrel Im running the comp beehive valve springs. I have only heard good things about them.
