[QUOTE="Monkeypants, post: 55091, member: 2708"] two spark plug holes in each head already, both in use and no place for a third. I dont think a different type of decompressor would be of advantage for kick starting as the stock item, once modified for Terry's Mk5 cams, works great, tho it is a complicated little affair. The problem in starting is that no matter what decompressors are used, the motor must roll over top at least once under full compression in order to start. Fortunately, with the short space long space geometry, this just barely possible at the end of the long space before compression( rear cylinder) The big squish bands which Terry designed into the heads make this engine much harder to kick over than a standard head version would be at same displacement and cr. The compression buildup with the hemi head is more linera wheras with the squish heads you really hit a wall when bringing e piston up within 40 thou of the squish bands. The extra lof the cams vs mk1 or mk2 is also noticeable on the roll up to compression. Because of the high lift(.440" vs .312 mk1 or .343 mk2, there is quite a [/QUOTE]
