Jeep Strokers

It works!!! At least I hope. Should be fine, ya?

53021676ab averaged about .630 ID, .890 OD, 9 grams
The comp spring has a .650 ID(top), 1.013 OD (top), 47.5 grams

I take it those aren't Jeep valves?
My 2001 has the 3 groove keepers, I'm not familiar with what the earlier single-groove ones look like.
Jeeps have 8 degree keepers, correct? ...and you're using 10 degree for those valves? What are they from?

I like the beehive option. But I'm past the point of sending the head back out to have it machined for springs.

It appears performance cams require more seat pressure than stock to keep the valve from bouncing off the seat. I'd guess cams with faster open/close rates like the Comp extreme series need more pressure than a milder cam.
Open pressure appears to be related to preventing valve float at high rpm's. Valve train weight comes into play as well..... heavier components need more spring pressure to keep things under control.
Would you guys agree with those statements?

I would agree. I'm using a 93 7120 head, which came with single groove keepers. The valves I am using are aftermarket Magnum oversize 2.020/1.620. They are a bit longer than the stock ones for my 97, but I threw away the original valves so I can't compare. The keepers are 8* Mopar (bought them blind on ebay for $12) which work with the hemi retainer.

Good work. Now it's time to get the new setup installed in the head and measure up the cc to see how it's changed (if any)

I've been participating in the thread with great interest and am suprised how many options there are and even more suprised there isn't a solution from one of the cam suppliers . Mopar Performance provides springs that would work but at $250. In my search, I reread Dino's site and found he had switched back to the stock cam and was able to generate 200 HP at the rear wheels or 5 ponies more than the original engine, pretty good. what might happen if an OEM cam was used while increasing the rocker ratio from stock of 1.6 to 1.7? lift would be increased allowing this beast to breath better. I would still be within the range of $6-$7 dollar ea springs P4529214 or P4529215 . This would increase the intake from 0.408" to 0.434" and exhaust from 0.414" to 0.440". Based on the Mopar chart we should be fine, right? Thoughts anyone on whether this would work or even provide benefit?
