did you use valley gaskets with the intakes ? i made that mistake once.

I would run a tap into the bolt holes as well

Yup, did that also..


My brain is cooked..Spent a whole day yesterday pulling all the studs..cleaning out threads, sealing..everything done right..filled system with water and pressure tested.. and I still have a LEAK!!! Nothing changed..leaks down just as fast..I hear nothing..see nothing..I left the blower off and valve covers off to see if I see a leak..nothing!! 13 days and counting...

try pressure testing it with the distributor out & use a borescope or a mirror to look under the intake for a leak.

We think a like..did that..no leak there..

I pulled the heads off and sent them to shop to get pressure tested.

Nope..used "The right stuff". When I pulled the intake off this last time..RTV was pressured equal also on all 4 ports.

to bad you live so far away,i have a 1000 hp engine sitting in the shop you could use for havazoo.

Update: 3" crack in one of the heads. 12 days till Havasu. Find out Monday if repairable. RHS heads. Less than 30 hrs on them. Never overheated. Not like!!

At least it is not the block; hope it is easily repairable!
