Has any body tried KA 24 or nap z duel valve spring on a 22r head. Nobody has any 22r springs available right now so thats my only option. I heard it work but I want to make sure.

 

Have u tried lc engineering. Or engnbldr 460rv. Springs ... even DOA there's some companies out there its more up to wich cam you intend on running ..

 

Agree. LC engineering is the place to get em.

Be forewarned though. With the dual springs, you also need the special retainers. And need get the hardened locks. Hell if your that far in get the bigger valves while your at it. Dont want a 30 yr old factory valve ruining your motor. Gets expensive

I cant get my valves to be quiet either. I blame it on the stiff spring pressure.\

Why exactly do you need upgraded springs? Ive spun 2 sets of stock springs in 2 different heads up to 6 grand without float.

 

Mine are loud to thing sounds like a sewing machine on crack .

 

Chelu, I've heard of a couple ppl running the dual springs off the mazda trucks. I think the B2200...? Not sure how good they work, but try asking around...

Thanks guys I am running a Web 292.LC duel springs are like $160 some and right know I cant afford.

 

Well. If your on a budget check out engnbldr.com they have. The rv 460 springs been using. Them for years on several high lift cams

I raced a couple weeks ago and on the way home I was getting a crazy vibration and knocking. First I thought it was maybe a loose fly wheel. So I dropped the trans and the flywheel was good and tight. I went ahead and changed out my trans anyway. I ran the motor again and still the same so I dropped the oil pan next to check bearings and the con rod and main bearings were all fine. I replaced all bearings and checked the thrust and it was good. So I was thinking maybe a bad wrist pin on a piston so I pulled the head and found notches where my exhaust valves had hit the piston heads. It hit on all four but #3 and #4 where the worst. I'll put up a pic of the worst notch in #4. Since I am running a 292 web with sides I think I stressed out those stock springs too much.

 

Thank you scrub88 I will checkout enginbuilder. I just wish it didn't take so long to get to Guam I hate waiting for parts to arrive.

 

Heres some pics notice the #3and#4 chambers are cleaner.

 

That's pretty cut and dry there. I'd check that valve probably bent how high did u rev it.

 

If all 4 touched the pistons I would replace all 4

 

Yes new valves are going in. I emailed engbldr and they dont sell dual spring kits anymore. That sucks.

 

Play-Doh your pistons when you go back together bro.

See how much clearance the valves have. A piston and rod can stretch as much as .030 inches. So roughly the thickness of a headgasket should put you in the clear.

 

Na they don't have dual springs just the RV 460 springs I'm running those on a 298 cam with 441 lift do you have the specs on that cam my first motor I ran a very grumpy lc stage 3 on single springs ran fine minus the street manners

 

Tha Web 292 has a lift of .515. I went ahead and ordered the dual springs from from LC rated to a max lift of .550
