Hello all I am building a Cirrus 1/4 scale as per Zimmerman design and using SIC drawings. I have built all the bottom end including cylinders and pistons and my next task is the oil pump and distributor, followed by the heads. As it is all complete to this stage and I like turning it over by hand to see things move ect. I was going to make the head holding down bolts to secure everything. I have gone through the plans NO drawings for them even though the write up in SIC quotes them. I have searched on line and the nearest I can get is pictures of them. So does any one out there have drawings for the cylinder head bolts for the Cirrus 1/4 scale by Zimmerman as described in SIC.
