It's not that bad! Â*I had to pull my heads off 3 times this year!

Some suggestions:

Why are you being warned about future blown gaskets? Â*Just get good gaskets. Â*I would suggest FelPro 1074. Â*They will give you .5 more compression and handle a fair amount of boost or NOS.

There seems to be mixed feelings about the Comp Cam Type-R lifters. Â*I used them on two engines without any problems, you just need to make sure you lash them correctly. Â*

Â*My other suggestion is that you should look into running an electric water pump. Â*If you switch to a E.P. you can run a double roller timing chain that cost about $60 as oppose to the big buck LT4/ heavy duty GM timing chain.

Â*Depending on how big a cam your installing or possible future mods I'd also suggest porting the intake to accpet a 58MM Â*throttle body. Â*Now a 58mm is too much for a 305 or Hot Cam, a 52mm will be more then enough, but you might as well port the intake while you have it off.

At best it's a full two day job if you have some help AND don't have any problems. Â*The big issues on the LT1 is the removal of the collant tube that connects the two heads, removing the crank hub. Â*Then for the install getting all the seals in the timing chain cover on correctly so they don't leak. Â*There is just so much crap on the front of the engine to remove that takes allot of time. Â*

Main thing is to take your time and keep everything clean.

I have a very detailed write up, somewhere? Â*It was done years ago my the MAFBA crew. Â*I'll try to find it.

Here are a few on-line write-ups that I know of.
