Hi guys. I've read somewhere that a few members here have run the RHS heads and have had issues with fitment. So, after coming up dead in my search around here I'm hoping those with some firsthand "hammer and weld" experience using these specific castings or even any other raised exhaust port SBF heads on 8.2 deck height blocks will chime in here. The ports and fastener locations are very close to .350" raised from OEM stock spec's. I did notice that ESampson has/does use these same heads but couldn't access his imageshack album from some old links he posted on a spark plug thread around here. Pictures would be pretty awesome to see and save much texting and reading on your ends too. What specific headers did you use? What specific header mod's and their exact locations? Shock tower mods? Other fitment issues?.. starter, oil pan, shock tower, slave cylinder.. pitman arm.. etc. Normally I wouldn't care and just chop and weld my way towards horsepower paradise.. but I'm going to be using these heads as an interim buildup on top of my old factory filled short-block and already have what look to be Hooker 6901's(or whatever the Hooker part # typically thrown around here) that I need to use to avoid custom headers. At least until I can get back over to my Kasse P-38 high-port conversion later on next winter after work slows back down again and I actually have a bigger "dusty stash" of higher dollar parts saved back up to continue on with. Just too damned expensive and time consuming to do all in one shot.. don't know what the hell I was thinking.. I'm not even close to being rich and this stuff usually takes me years to accomplish on the limited allowance my wife gives me. Main motivation is probably like some of you too.. my boys are bugging me more and more to quit screwing around with all the full-on racing parts so we can more quickly get it together this year for the car Craft Summer Nationals in July 17 - 19. Plus, I figure they're growing up so fast(13 and 15) that they won't even get to enjoy it as much by the time I finally get through with all my crazy idea's and rubber meets the road. They've also heard me talk about "massive snow-tire burnouts" so many times through the years that they want us to enter the Comet into the burnout contest. Not sure if we'll have time and cash needed to swap to a trac-loc setup and get rid of the lazy 2.79's for full effect.. but I surely know that even one snow tire can make one hell of a cloud all by its lonesome if you spin it fast enough. Let's see.. 3rd gear x 2.79 gear ratio x 7,200 rpm?.. = "hey, where'd he go?.. we can't see him any more!" lol Fairly mild street build by my standard.. up around 400 horses/decent street torque with smaller cam/big dual plane/small tube headers. Oh crap. Almost forgot to mention the most major concerns I have with header fitment here. My "already raised .350" ports will be modified and lifted even further(another .100" thou or so.. to .450" total) and the header will also need to ride up a bit higher with slotted holes on the flanges to allow proper port matching. But wait.. that's not all.. just to seemingly make things even more unnecessarily difficult for myself and so I can start to lose my hair even faster.. and make matters even worse at the shock towers.. I want to lower the engine into the cradle a bit deeper than the factory location. At least a full inch drop would be nice to find and I would also consider moving it back towards the firewall while I'm making custom fitted parts. This of course counter-offsets all of the raised ports geometry changes in final tube height.. but causes them to be even nearer the shock tower. But.. if that's pushing too hard and too fast and causes too many additional issues.. the stock mounts can be used for now if need be. So, nutshell time finally. The headers will sit approximately 1 1/4" wider at the flange because of the additional raised port height.. and also down into the narrower section of the shock towers by about 1/2" or maybe slightly more. Is that even possible to do with a hacked up set of off-shelf headers and uncut towers? Any constructive input, pictures, or thread links would be great.. thanks ahead.
