You do know you can now buy a complete single composite intake/pan gasket from TA, about $30.:beers2:
There is also a separate valley pan without the intake gaskets from Mike at AM&P, you can fid it on e-bay.
Yes, he has milled down heads which change the gasket thickness needed. Using non milled heads the X-Factor can use a regular gasket.
Marty, What I have found is that solid lifters use a snap ring and hydraulic use the U shape wire. Is yours a solid? Chris
Nope: these are hyd. with snap ring, probably copies of the Comp Cam ones Guy uses. Part # is 71969PR. They have a much larger oil hole in the plunger cap than the old U wire type.:TU: Nicer looking box too!...Says PERFORMANCE Flat Tappet Lifters.:Brow:
Make sure the bottom of the retainer doesn't touch the top of valve stem seal with that 1.65 rocker ratio, and your 67003 cam lift. Could be distorting the seal some. I cut guide bosses down quite a bit and only have 1.6 ratio rollers. I use the teflon seals. My head shop set my bronze guides at int.= .0012-.0013, and exh.=.0016-.0017 clearances. No oil consumption or smoking.
I have never used the valley pan gasket...only the composite intakes. I moved the pvc to the valve cover and use a small motorcycle air filter at the intake mainfold...this works best as the manifold crossovers are blocked and thus no need for the valley pan. If your heads are milled at all the composites make it alot easier to align the ports as the shim gasket is set in stone. Using the two combined seems like an invitation to problems.
Here's 2 pics of the old(left) and the new style(right) Lunati sent out. Which ones are the best to use for normal oil control to the top? Notice the lower & larger side oil hole position, and the larger oil hole in the cup on the new style. Curious as to why they are very different.
Because they're made by two different companies? Lunati does not make lifters. Comp Cams does not make lifters. There are about four companies that make lifters, and they sell in bulk to four hundred others who put them in custom-label boxes and sell to YOU. Pull 'em apart, you may be able to identify who made them based on the parts inside. Or maybe not. I took my "Pontiac" Lunati lifter apart, and it looked like a cross between two of the lifter four styles I'm familiar with. But my lifter identification chart is old, and perhaps the companies have made changes I'm not current on. Keep in mind that the VISIBLE oil hole you're comparing is not the size of the metering orifice and has NOTHING to do with the amount of oil flow out of the lifter.
The Lunati Pontiac/Olds lifter I inspected: The oil metering disc is the dark, round, stamped sheetmetal item third to the right in the top row.
