Doug's headers install

Tonight I reinstalled the suspension componets and the starter. One snag I ran into is that the transmission supports (which are on both sides of the motor running back to the transmission,) are in the way of the headers. SO I've had to notch them(a lot!) Not sure how much support they'll offer now, or if they'll even fit after being notched? Second little snag... the driver-side header is ever so slightly warped. I could get 5 out of six bolts started into the heads... but the sixth bolt would not thread in. I just took my time backed them out rethreaded, several times until I got all six slightly threaded in... then as I tightened them down(criss cross) the header sort of "popped" into place and the bolts threaded with ease. So I think it was slightly warped OR the holes are not drilled out with the most precision. Third snag... #2 bolt drivers-side (pic) Would not slip past the tube... so I did a slight grind on one side of the hex head just to get it to slip past the tube.(A tap with a hammer might work too... but would I ever get that bolt out again?).

Question... I want to replace my 90' oil filter adapter for one that threads directly into the block... and I want a stubby oil filter. Anyone know a part # for these items? Also what should I use as heat protection on my starter and the wires running from the battery to the starter? Thx :-D
