Reply to "Cylinder head choices"

Tai, if you wish to get deeper into the subject of closed-chamber heads, I'll give you another reference book: 'Racing Engine Preparation' by Waddell Wilson of NASCAR fame (Steve Smith Autosports, publisher). In it, Wilson talks about 'posting' Boss heads, to keep the combustion chambers from flexing and reversing water flow through the engine at high revs.... In the April POCA newsletter, I sawed apart 3 cracked Cleveland heads and wrote an article on the coring, cooling mods and a pictorial of the miserable oil drain-back holes we have to deal with. I also showed the effect of such 'posting' supports and the somewhat controversial subject of adding air-bleeds to the back of 351-C heads to prevent spot-overheating.
