Best Head Bolts for SVO 2.3?

I recently ordered head bolts for my 85.5 svo engine from summit racing. The bolts were described to work for ALL 2.3 engines from 74-93. I put my head on the block and dropped the bolts into the holes to realize that the thread on the old bolts were 1/3 the length of the new bolts so i now need to find the right bolts to complete my motor as soon as possible im tired of bumming rides and taking the bus when i have a gorgeous SVO sitting with no motor. my engine has a worked head w/ oversize valves bigger cam ported and polished intake and exhaust manifold and the boost is bumped to 19psi, but im trying to run methanol and go to 23psi while the stock turbo is still pulling strong. Idk if any of that info helps you find the right bolt but its worth a try. if you can please provide the manufacturer of the bolts and where i can get them thank you you guys are the best :smoke: Thanks for your time
