[QUOTE="ClassicBiker, post: 107461, member: 1632"] Update: Last week I removed the remaining guides and measured their o.d.s and the i.d.s of their respective holes. Both inlets measured 0.501 as did their respective holes. A light tap with a drift and raw hide was all it took to remove them. The rear exhaust was 0.564 and the hole was 0.563. Rather than beat it out with a drift and hammer, I used a length of threaded rod and made a puller which eased it out in a controlled manner. The front exhaust hole was 0.568. So I'm thinking for the inlets 0.502 for a slight interference fit, 0.564 again for the rear exhaust and seeing what the Spares Co. has for extreme oversize. I also measure the depth of the recess in the heads that the liner spigot into and how proud the liners stood above the muffs. Looks like I'm going to be spending some time with some emery on the surface plate. Steven [/QUOTE]
