whats my Horsepower gain with these mods?

Why do V8 guys insist on commenting with such venom on slant threads?

Go search "ported slant head" thread. That's my head. Does that look like a V8 to you? I made the smartass (not venomous) comment because I was makin fun of the exhaust tip when he made no mention of exhaust mods whatsoever, which is where he would see the MOST GAINS. In other words, I was jokin with him, not being "venomous". Evidently, you would hide under a table if people really did get venomous. Go stereotype somebody else, moron.
