Trying to find a set of shims to fit uncut heads with .015, .030, and .060 shims. Not having much luck, any suggestions?? TIA, jess in ky
They should be readily available from a machine shop, TA, or Summit Racing. You just need to know your spring ID and OD
The springs I want to use are TA Performance's 1435A Stage 1 Plus springs, they show the OD as 1.265 (doesn't give an ID). The actual factory machined seat measures 1.350 OD and a shade less than .850 ID. I would like to find an assortment of 16 each of .015, .030 and .060. TA doesn't show ANY on their website (haven't called yet) Summit has a large listing, but no kit that includes all three sizes. The hunt continues!! jt
The base of your valve guide OD that the valve spring locates on is ,865”, that much I can help you with . Be sure that the shims you finally do get are harden.
I can't believe that there are Buick specific valve spring shims. They just go by size. These are the ones Jim used on my build. Just PM Jim Weise.
Thanks, but those won't fit over the .865 valve guide/valve spring locator on stock heads. " Just PM Jim Weise " Did that, still waiting. The hunt continues. jt
One phone call to TA Performance on Monday will solve your problem. http://taperformance.com/ I'm sure any machine shop that rebuilds engine/heads could help you as well. I see you are in Kentucky. E mail Mike Phillips, ampmike@aol.com. Mike used to build killer Buick engines for Automotive Machine and Performance in Philpot. http://automachperf.com/
Sorry to hear that, prayers to Jim and his family. I have tried to call TA Performance, no doubt out for the holidays. No problem, I will call them next week, (will keep Mr Phillips in mind). Thanks all. jess
Stage one plus springs require the valve guide to be cut, it’s a smart upgrade to do while the heads are apart and allows use of a dual spring and the smaller stem seal
I had mine cut down to fit .500 seals and shorted the height when I used my plus springs. Worked well on a .550 lift and .575 cams we ran. Not sure how much more they will go, but we had no control issue at .575 lift and 6500 rpm
