Aight, so I went ahead and bought a set of new assembled SCJ heads (insert happy dance here). I also got a set of stamped Trick Flo valve covers. To my utter surprise, they don't fit.. Looking at the head from the intake ports side, the far right exhaust valve is angled over towards the cover in such a way that the stamped cover will not fit. It has the cover pushed over almost 1/2 inch away from the bolt holes lining up on that end. Now, here's my issue. I went with the stamped VC's because I was trying to save room near the brake booster as it's gnna be tight there. (90 LX Foxbody) I really don't have the room for the big sheet metal VC's. I did find a 1.4 in spacer from Steff's fabrication that will let me use the Trick Flo VC's, but here again that's gnna be as tall as the big sheet metal ones... Does anyone know what VC's will fit the modern SCJ heads without being so huge or big and bulky?? And yes as a last measure I'll do manual brakes, but I really don't want to as I'm disabled...

Stamped valve covers with the OEM style baffle won't fit properly due to interference in two places. The aforementioned exhaust valve spring's proximity to the valve cover rail.
In addition the baffle that would normally fit in between the valve springs in the stamped covers hits the springs.

We've used the BT cast covers with simple clearancing and drilling the bolt holes a tic larger. 1643 Felpro gasket.

The fabbed aluminum short valve covers work well as is with a 1643 felpro gasket.

Double check the areas of interference.

I just saw this post. I know I'm late to the party but I'm not that late.. Maybe I should know this already but I don't. Do you street drive your car and/or could you go with a different master cylidner set up? I put one of the manual master brake cylinder kits on my car from Skinny Kid Racing. It comes with a new aluminium mounting plate that moves the master cylinder over to the outter fender for a bit for more room. The manual master cylinder itself is also pretty small. I had no trouble getting it fitted up and installed myself. Now I have NO trouble getting my valve covers on and off.....and I got BIG valve covers. I don't know if that's an option for you but I thought I'd throw it out there. That master cylinder also had no trouble stopping the car. If you have to press harder I don't really notice but I'm a big fella. It still stops easy.

This is the kit I'm typing about..

I may have to bite the bullet and go that route, (Thanks for the link!!) I don't think my plan C (making a set of valve covers out of plywood) is gnna work out too well 😂🤣... If I can't get enough pedal stomp, the bracket moving it over will help out with room if I go hydro boost.. Right now I'm trying to decide on wether to get a set of spacers for my covers, or get a different set of covers altogether..

Edit: Sorry I neglected to mention that it's gnna be a street driven car with only an occasional trip to the track. I am disabled and don't have the strongest legs, but I do realize that with manual brakes that they work better when you pump em up! Something gen X knows nothing aboot!
