Those lifters may uncover the oil gallery in a stock 109 block. They will work in a Stage 2 block or if you bush the lifter bores.

hey thanks guys for your info the lifter bores were bushed by my machine shop getting the 206/206 billet cam so the lift isnt that big but not really sureon what the lift is but what ever it is i know the 1.65 rockers will make it a little bigger .still have to get the springs to mach the cam .and after i put the heads on i have to measure for the correct lenght pushrods .have been thinking on what head gasket to go with rjcs or cometics on the gn1s 8 bolt head.please give me more input thanks again norbs and turbodave .
Assuming your building a 109, why did your machine shop bush the lifter bores? With a little shaft(206), bushing the lifter bore isn't necessary. If you are going to use a solid lifter in conjunction with a billet cam shaft, you can put a good size spring on your GN1 heads. I use a PAC BBC beehive setup. Also, I use cometics with studs on my M&A aluminum heads without a problem.
yea i went and checked the the worksheet they just honed the bore not bushed, so the behives pac bbc wil work on the gn1s whats the lode on those springs the person selling me the cam said that he used the comp 941-12 but he had cast head dont know if that spring will fit on the gn1s if not then i would have to get the bbc behive pac .like cme2fly stated .so i would have to set the valve lash at .006-.007 at tdc.like norbs stated .man guys thanks for your time really needed your experience hear .thanks again.

ok thanks guys it is a hydrolic roller cam so i can use these tappet on them so long i dont go over 540 lift and the lash at .06-.07 thanks did one of you say that you used these tappets on m&a heads with cometics what length was your push rods ? i would guess that that would depend on the lift of the cam .so it most likley wouldnt be the same.thanks again .

If your cam is a billet core then you can use the solid roller lifters. I wouldn't worry about valve lash at this point in the game. Your cam probably doesn't have enough lift to expose the lifter oil gallery. Push rod length is going to vary depending on application.
