grinding down intake rocker bolts...

how are you guys grinding down your intake rocker bolts so they dont protrude down into the intake port...are you guys angling them or just flat grinding each of the intake bolts so wichever thread you start the bolt with (two right) either way the bolt will not protrude (hope this makes sense)...every little bit counts when it comes to max power/effort stock ls6 346 combo

I ground mine down to match the radius of the runner for a smooth transition.

Are these the stock size (other than length) or would these fit in a Harland Sharp modified rocker?

I was either thinking of grinding mine or getting some washers, to shim the bolt up a bit.

Before swapping bolts, did you check your wipe pattern? You may find that shims are required to correct the wipe pattern and the rocker sits higher resulting in less bolt intrusion into the intake runner.

Does the ARP sealant remain pliable? Curious as this may be a good option for me as well.

Thanks

I used Loctite PST with teflon thread sealer. It doesn't harden and seals great.

I just used a permanent marker to draw on the exposed part of the threads and then cut with a dremel. It has to be torqued to spec each time, otherwise the angle will be off.

I just ground down the 8 intake rocker bolts last night. Used a bench grinder and just ground the ends off just before the threads to aviod damage. Took 15 mintues...

Any reason not to use regular locktite to keep the oil out?
