I'm completing the work on my Model A engine and I'd like to get some help on thehead. I've checked the archives . I bought the Dan Price head and as some ofyou know, consideration must be given to clearance between the head and thepistons. At TDC, my pistons are .045 above the deck. if I cut too much clearancein the head, the compression ratio will be lowered. If I cut too little, thepiston will strike the head. Sufficient clearance must be allowed for carbonbuildup and thermal expansion of the rod. Can anybody out there give me someguidance on a procedure for determining optimum cllearance? I would appreciatthat very much........Carl Vought________________________________________________________________________________Date: Wed, 29 Mar 2006 19:40:25 -0800 (PST)

Ken Perkins does a .060 flycut (matching cylinder bores in a Model "B" head gasket)in his Alum. heads so the pistons won't get cracked due to carbon build up.He is in www.mykitplane.com in the Pietenpol listings -- he'd be the one to talk to on the heads (& etc.) -- His engine did it's stuff in 2004 for my Piet ride at Brodhead!! ;-)Mike C.Pretty Prairie, KS ----- Original Message -----
